Consider the following C function f() :
unsigned int f(unsigned int n)
{
unsigned int b=0;
while(n)
{
b+=n&1;
n>>=1;
}
return b;
}
The function f() returns the int that represents the___p___in the binary representation of positive integer n, where P is
1
number of 0's
2
number of bits
3
number of consecutive 1's
4
number of 1's
