For all those that couldnt get the 1634 test case right in the armstrong questoin, the power of each digit is equal to the no. of digits in the number for example : if it is a 4 digit number (1634) , then (1^4)+(6^4)+(3^4)+(4^4)=1634 if it is 3 digit then instead of 4 power will be 3 heres the code: #include bool checkArmstrong( int n) { string digits=to_string(n); int digitcount=digits.size(); int num=n; int r=0; int pal=0; while(n>0) { r=n%10; pal=pow(r,digitcount)+pal; n=n/10; } if(pal==num) { return true; } else return false; } might not be optimal but it is how i tried and it works
is this correct as well ?? what about time complexity??? { int i=0; int N = 371; int duplicateOfN1 = N; int d2 = N; while(N>0) { N=N/10; i++; } int sum = 0; int digitcount=i; while(duplicateOfN1>0) { int lastdigit = duplicateOfN1%10; duplicateOfN1 = duplicateOfN1/10; sum = sum+((int)Math.pow(lastdigit, digitcount)); } if(sum==d2) System.out.println("it is an armstrong number"); else System.out.println("it is not an armstrong number"); }

23:55 One correction !! Armstrong number is the number in any given number base, which forms the total of the same number, when each of its digits is raised to the power of the number of digits in the number. 1634 is not equal to 1^3 + 6^3 + 3^3 + 4^3 it is equal to 1^4 + 6^4 + 3^4 + 4^4
Can u provide the code for it am doing cmath and using pow function to use the number of powers equal to total no. Of digits but in 1634 its giving false

25:25 this Armstrong number works only for 3 digits If you want to find less or more than 3 the approach should be 1. Find the number of digits using int i = (int) log10(n)+1 2. While loop n> 0 3. Extract digits using n%10 4. In the while loop use pow(digits,i) function to get power of that digit 5. Check with the original n outside the loop

Hey Striver, I am a 5th semester student of a tier-3 college, first of all thankyou for all your videos, I have completed your graph series, almost completed your SDE sheet. I needed your help so I joined your channel. I see that your last members only post was a year ago, I understand that u have a full time job and therefore you are busy. I just wanted to know if you will continue making meeting sessions, because I need your guidance. Thanks again for your hard work.
In the eucledian algo why we are taking min(a,b) in time complexity like the time complexity should be logphi(max(a,b)) Because we take max of a, b and divide that. Like in count digit we write log10(N) where N is the number divided by 10, so here max(a,b) is the dividend in eucledian algo
Your video is very informative. I can learn new things from every video. I knew all of this topic. but your video taught me new things, and how to think clearly. Thank you, sir.
Thank you striver for explaining all the basic math stuff mostly in other courses the instructor assume that we already know they simply explain the code.
Striver your video is superb.. and in each video you taught in a very energetic way which makes your video very interesting. All the part in the video is amazing but the last.. i.e. Euclidean’s theorem and reducing loop by half by sqrt.. method is wonderfull.. Now, I try to build-up this type of logic in every Q. to reduce time & space complexity. Thankyou Striver ❤
Understood.. for armstrong number here's my java solution : public static boolean isArmstrongNumber(int n){ int x = n; int sum = 0, count = 0; for(int i = 1; i < n; i *= 10){ count++; } // while(x > 0){ int ld = x % 10; sum += Math.pow(ld, count); x = x / 10; } return sum == n; }
Understood. Today is November 19th, 2024 and i have just completed watching this video. I will come here periodically to update my status and my offers! Wish me luck!
24:15 bro did a mistake which was noticed already, An Armstrong number is a number that is equal to the sum of the nth powers of its digits, where n is the total number of digits in the number. For a four-digit number, the power used for each digit would indeed be 4, not 3. Refer to the link for better understanding, th-cam.com/users/shortszrrLbXFEjtY?feature=share
there is a small mistake you take a number 1634 is equal to the 1^3+6^3+3^3+4^3 but armstrong number is a number which is equal to the sum of digits to the power of how many digits in a number ... 1634 = 1^4+6^4+3^4+4^4 thanks 🙏🙏😇
very well explained sir i have just started the series and I am getting each and every thing . Your teaching methodology is just insanely superb. Please asap bring a linked list series as well sir
Hey Striver I wanna highlight one point about Armstrong number logic you have explained might not correct... You said any number if we make cube of its digits and if it's equal to original number then it's an Armstrong number but this is not always the case..For example you said 1634 is an Armstrong number (which is true) if you calculate cubes of each digit like 1**3+6**3+3**3+4**3 is not equal to 1634 Armstrong number is a number that equal to the sum of its own digits each raised to the power of the number of digits in original number So for 1634 Total number digits is 4 so we should calculate each digit raise to 4 so 1**4+6**4+3**4+4**4==1634 I see the gfg link you given has a test cases where 100
I think this way is simple for reversing number without the occurrence of '0'; void count(int n){ while(n>0){ int last_digit; last_digit= n%10; if(last_digit!=0){ cout
there is a small edge case left in case of reverse number we should check the condition for the overflow if (reverse > Integer.MAX_VALUE / 10 || (reverse == Integer.MAX_VALUE / 10 && lastDigit > 7)) { return 0; } if (reverse < Integer.MIN_VALUE / 10 || (reverse == Integer.MIN_VALUE / 10 && lastDigit < -8)) { return 0;
Understood , but there are a few things that can be changed according to the logic given in the question as per the solution discussed , like in armstrong number . Btw, got to know about time complexities , the approach for optimizing solutions and all other things .
I am very much grateful for the work you are doing for programming community. ❤ Below is the "Print Divisors" code with Sorting in JAVA, which is not available in A2Z DSA course platform under optimal approach section. Thank You 😊 import java.util.*; public class PrintDivOptimizedSort { public static void main(String[] args) { Scanner scn = new Scanner(System.in); System.out.println("Enter the number for which you want the divisors: "); int n = scn.nextInt(); System.out.println(); printDivisorsOptimalSort(n); scn.close(); } public static void printDivisorsOptimalSort(int n) { List list=new ArrayList(); System.out.println("The divisors of "+ n + " are: "); for(int i = 1; i
At 35:40 What if we do not use sort method. Instead, we store the i in a list and n/i in another datastructure stack so the biggest will be at the bottom and lowest at the top of the stack. And finally we use one more loop till sqrt(n) to add the item to the list like List.add(Stack.pop()); Will it take less time then the sort function which is O(n log(n)) Thanks for your time.
The palindrome problem can also run without including using namespace std; as --- bool palindrome(int n) { int reversenum = 0; int dup = n; while (n > 0) { int ld = n % 10; reversenum = (reversenum * 10) + ld; n = n / 10; } return dup == reversenum; if (dup == reversenum) cout
Let's march ahead, and create an unmatchable DSA course! ❤
There is a slight mistake on the logic of Armstrong, it will be 1634 = (1^4 + 6^4 + 3^4 + 4^4), basically digits raised to the power count of digits, so sum = sum + pow(ld, cntDigits) will be the change, where the cntDigits is the number of digits.

For all those that couldnt get the 1634 test case right in the armstrong questoin, the power of each digit is equal to the no. of digits in the number
for example :
if it is a 4 digit number (1634) , then (1^4)+(6^4)+(3^4)+(4^4)=1634
if it is 3 digit then instead of 4 power will be 3
heres the code:
#include
bool checkArmstrong( int n)
{ string digits=to_string(n);
int digitcount=digits.size();
int num=n;
int r=0;
int pal=0;
while(n>0)
{
r=n%10;
pal=pow(r,digitcount)+pal;
n=n/10;
}
if(pal==num)
{
return true;
}
else
return false;
}
might not be optimal but it is how i tried and it works
yeah u r right even i got this mistake in most of the google search results but chatgpt and gfg gave me the right answer
is this correct as well ?? what about time complexity???
{ int i=0;
int N = 371;
int duplicateOfN1 = N;
int d2 = N;
while(N>0)
{
N=N/10;
i++;
}
int sum = 0;
int digitcount=i;
while(duplicateOfN1>0)
{
int lastdigit = duplicateOfN1%10;
duplicateOfN1 = duplicateOfN1/10;
sum = sum+((int)Math.pow(lastdigit, digitcount));
}
if(sum==d2)
System.out.println("it is an armstrong number");
else
System.out.println("it is not an armstrong number");
}
Actually power =number of digits in the number so try with power 4 it will work .
Thanks it helped

If you want to find less or more than 3 the approach should be

2. While loop n> 0
3. Extract digits using n%10
4. In the while loop use pow(digits,i) function to get power of that digit

In the eucledian algo why we are taking min(a,b) in time complexity like the time complexity should be logphi(max(a,b))
Because we take max of a, b and divide that.
Like in count digit we write log10(N) where N is the number divided by 10, so here max(a,b) is the dividend in eucledian algo

You said any number if we make cube of its digits and if it's equal to original number then it's an Armstrong number but this is not always the case..For example you said 1634 is an Armstrong number (which is true) if you calculate cubes of each digit like 1**3+6**3+3**3+4**3 is not equal to 1634
Armstrong number is a number that equal to the sum of its own digits each raised to the power of the number of digits in original number
So for 1634
Total number digits is 4 so we should calculate each digit raise to 4 so 1**4+6**4+3**4+4**4==1634
I see the gfg link you given has a test cases where 100
Hi @Raj sir. Thanks for the video also Congratulations for your 300k subscribers. Looking forward for your more wonderful videos. Truly enjoying. ❤
Great content for any professional or an engineering student❤💯. Thank you sir for taking this much of efforts 💯
I was waiting from last 5 days. Finally come 😌😌
Perfect and simplest explanation found ever
I think this way is simple for reversing number without the occurrence of '0';
void count(int n){
while(n>0){
int last_digit;
last_digit= n%10;
if(last_digit!=0){
cout
Amazing. I loved the GCD part, understood very well. Thank you so much
Unstoppable striver for a reason 🙌❤
Understood! Super fantastic explanation as always, thank you very much!!
there is a small edge case left in case of reverse number
we should check the condition for the overflow
if (reverse > Integer.MAX_VALUE / 10 || (reverse == Integer.MAX_VALUE / 10 && lastDigit > 7)) {
return 0;
}
if (reverse < Integer.MIN_VALUE / 10 || (reverse == Integer.MIN_VALUE / 10 && lastDigit < -8)) {
return 0;
started dsa with your this course,thank you!
Understood , but there are a few things that can be changed according to the logic given in the question as per the solution discussed , like in armstrong number . Btw, got to know about time complexities , the approach for optimizing solutions and all other things .
your gcd explanation is awesome
God bless you brother, i am in better place all thanks to you!!!
Anybody in Aug-2024 or after
Me 😂

Me in September
Yeah bro 🎉
Make videos frequently bro,it will help for placements
I wish i would have known
abt this channel earlier rather than spending money on paid course thank u striver.
Bhaiya maza aa gya
Fully understood 😃😃
I am very much grateful for the work you are doing for programming community. ❤
Below is the "Print Divisors" code with Sorting in JAVA, which is not available in A2Z DSA course platform under optimal approach section.
Thank You 😊
import java.util.*;
public class PrintDivOptimizedSort {
public static void main(String[] args) {
Scanner scn = new Scanner(System.in);
System.out.println("Enter the number for which you want the divisors: ");
int n = scn.nextInt();
System.out.println();
printDivisorsOptimalSort(n);
scn.close();
}
public static void printDivisorsOptimalSort(int n) {
List list=new ArrayList();
System.out.println("The divisors of "+ n + " are: ");
for(int i = 1; i
thnx
In the mathematical observations part, at 36:00, isn't it will be easy and smart to use SET as a data Structure.
At 35:40
What if we do not use sort method. Instead, we store the i in a list and n/i in another datastructure stack so the biggest will be at the bottom and lowest at the top of the stack.
And finally we use one more loop till sqrt(n) to add the item to the list like
List.add(Stack.pop());
Will it take less time then the sort function which is O(n log(n))
Thanks for your time.
your teaching skills are awesome bro
The palindrome problem can also run without including using namespace std; as ---
bool palindrome(int n) {
int reversenum = 0;
int dup = n;
while (n > 0) {
int ld = n % 10;
reversenum = (reversenum * 10) + ld;
n = n / 10;
}
return dup == reversenum;
if (dup == reversenum) cout
What a brilliant way of teaching hats off to you and thank you so much for the content ;)
The best I repeat the best explanation ever💫
Great learning from the video ❤
understood!!!!!!!!!!!!!!!!!!
may god bless you striver bro.
started working on this a-z dsa course.. Have a job but want to start over these topics .. To switch to a better one!!!
🙏 🙏 🙏 🙏 🙏 hats off to you, preparing this videos require a lot of time and from your busy schedule you are preparing for us Thank you, Dada.
best one till now!!! 🙏🙏🙏
understood the assignment :) thanks striver
It's great to learn from this channel ❤️Thank you:-)
Congratulations for 300k bro 💕🥳.
And I've a doubt, is OOPS concept included in A2Z dsa series or not. A small doubt.
no bro
