Can anyone explain the time complexity in detail of solution 2? From my understanding, I know it is because numbers are 32 bits integer, then worst case time complexity is O(32) which is O(1).

[@nikhilpoonia8191]

please explain...i am not getting the code dry run

[@anushkasiddhu9554]

why can't we use the left shift instead of the right shift.

[@darshanv5200]

Instead of num & 1, I tried for(i=0; i>>1;} in Java. It didn't work for a few cases. Does anyone know why?

[@yatinarora1252]

Hii

[@puspaulmukhopadhyay7794]

why is this code not working ??
class Solution {
public:
int hammingWeight(uint32_t n) {

int cnt =0 ;
while (n!=0)
{
if(n%10==1)
cnt++;
n=n/10;
}
return cnt;

}
};
