190. Reverse Bits -- 按位反转
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).
Follow up:
If this function is called many times, how would you optimize it?
class Solution { public: uint32_t reverseBits(uint32_t n) { uint32_t ret=; for(int i=; i<; i++) { ret = (ret*) + (n & 0x1); n /= ; } return ret; } };
