Question
Reverse bits of a given 32 bits unsigned integer.For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as 00111001011110000010100101000000).
Solution
[code]uint32_t reverseBits(uint32_t n) {
uint32_t result = 0;
uint32_t i = 0;
for(i = 1; i != 0; i <<= 1)
{
result <<= 1;
if(n & 1 == 1){
result |= 1;
}
n >>= 1;
}
return result;
}
