Solution: Number of 1 Bits

Statement▼

Write a function that takes a 32-bit binary representation of an unsigned integer $n$ and returns the count of its $1$ bits.

The binary representation of an unsigned integer is a sequence of $0$ s and $1$ s that represents the integer's value using base-2 notation. An example of the 32-bit binary representation of an unsigned integer $13$ is $00000000000000000000000000001101$ . ...
