excellent explanation.need more programs depend on ds programming interview questions
Very well explained 👏
Thank you so much ❤️
Welcome
All of your programs that u r explain is excellent
Thanks
Hello! I recommend using a while loop instead of a for, so you can use flags (Boolean, i.g. while(!found && i
i am taking input from user and not adding break and still it works fine
Thank you. Excellent teaching skills
You are welcome!
Excellent. more useful for me. i shared with my frined s and collegues also. please do more concepts on searching and sorting techniques
Thank you so much for your help!
Welcome
Thank You so much Sir.
You are most welcome
Bro excellent teaching skills please do more videos on programs & on concepts too
Sure.I will do, Please share my videos to your friends and colleagues.
Can i use else statement after founding the element and print the statement
Instead of Boolean can We use else Condition?
Thank you sooo muchhh
Welcome
thanks
Welcome
Is there any problem if I take boolean flag as True at starting
Can we write else part inside for loop ?
you can use else. But in this code, it will do the else block for every iteration that it is not equal to the element.
Sir,As we have break the loop why the statement System.out.println("Element not found")work outside the for loop?
Break statement is inside a loop...so the loop will break upto it...
superb sir... i have a doubt if the array is to be got from the user...... it should be in a for loop... how should be the scanner should be.... pls explain
Scanner sc=new Scanner(System.in);
n=sc.nextInt();
int a[]=new int[n];
for(int i=0;i
@@renjithu8078 thank u
thanks!!
Welcome
Sir can we write "break" also in else part ?
No need it will automatcaly break
Does break; statement needed here?
if you not break the loop when the element is found, the loop still runs, the adv is it saves space, if not break, if the input is {10,20,30,50,50} it gives two times the search element is found at 3,4
sir what if there are two 20 value in an array???
1st occurrence will give the output
Commenting for better reach
that's very kind man
god bless u
If I do this program with enhanced for loop then what to write if I want to print index position
public class Code{
public static void main(String[] args){
int a[]= {10,20,40,50,30};
int srch_ele=30;
boolean flag=false;
for(int i:a){
if(srch_ele==i){
System.out.println("Element found" + ); //for index position
flag=true;
break;
}
}
if (flag==false){
System.out.println("Element not found");
}
}
}
in enhanced loop you cant access the index position
