LeetCode. Inverted bits

Topics requirements:

Reversed given 32-bit unsigned binary integer.

Example:

Input: 00000010100101000001111010011100
Output: 00111001011110000010100101000000
explained: 00000010100101000001111010011100 input binary string unsigned integer 43261596,
the flow returns 964,176,192, which is 00111001011110000010100101000000 binary representation.

Code:

class Solution {
public:
    uint32_t reverseBits(uint32_t n) {
        uint32_t result = 0;
        for(int i = 0; i < 32; i++) {
            result <<= 1;
            result = result | (n & 1);
            n >>= 1;
        }
        return result;
    }
};
