[@tusharsharma6715]

awesome bhai.... nice way of explaining

[@HelloWorldbyprince]

It's my pleasure

[@shaantyagi2187]

Done before watching the video!
#include
class Solution {
public:
int getDecimalValue(ListNode* head) {
vector v;
ListNode* temp = head;
while(temp!=NULL){
v.push_back(temp->val);
temp = temp->next;
}
int ans =0;
int j=0;
for(int i=v.size()-1;i>=0;i--){
ans = ans + v[i]*pow(2,j);
j++;
}
return ans;
}
};

[@HelloWorldbyprince]

nice solution

[@yashpandey7]

Insted of string to int ,we can directly use the val and multiply It by every time.
Just see below code.
int sum = 0;

while (head != NULL){
sum *= 2;
sum += head->val;
head = head->next;
}
return sum;

[@HelloWorldbyprince]

yess dude we can do this way

[@yashpandey7]

[@radhehirapara4707]

I like this logic

[@HelloWorldbyprince]

Thanks a lot

[@MOHITRANA-to7rf]

bhaiya why we cant use this this approach in linked list
void display() {
struct Node* ptr;
ptr = head;
int count;
while (ptr != NULL) {
int binary = 0, count =0;
if (ptr->data == 1)
{
count+= 1**(binary);
}

// binary++;
ptr = ptr->next;
}
cout

[@sudarshan_9]

Thanks Sirji

[@HelloWorldbyprince]

Your welcome sudarshan

[@Brainradar01]

Bhaiya doubt
In function binary to decimal
If s[i]==1
Dec+=base
base *=2
Else
Base*=2
This is the correct code bhaiya
For example 101 = 5
For 1 base got multiply with 2 and dec get added
But what about 0 else part the base should definitely multiply with 2 then we will get 5 answer otherwise get 3 wrong answer please reply if i correct or correct me ❤ resp+

I tried doing the same code on LeetCode, but it's showing memory limit exceeded. Can somebody please resolve this?

,it can be done using bitwise operator only in one iteration
