LeeCode-Number of 1 Bits

Write a function that takes an unsigned integer and returns the number of ’1' bits it has For example, the 32-bit integer ’11' has binary representation 00000000000000000000000000001011,so the function
should return 3.

int hammingWeight(uint32_t n)
{
int count=0;
while(n)
{
n=n&(n-1);
count++;
}
return count;
}
