Flipping bits hackerrank solution in python
WebFeb 24, 2015 · You will be given a list of 32 bits unsigned integers. You are required to output the list of the unsigned integers you get by flipping bits in its binary representation (i.e. unset bits must be set, and set bits must be unset). Link. Flipping Bits. Complexity: time complexity is O(N) space complexity is O(1) Execution: It can be done by either ... WebSimply use the bitwise not operator ~. int flipBits (int n) { return ~n; } To use the k least significant bits, convert it to the right mask. (I assume you want at least 1 bit of course, that's why mask starts at 1) int flipBits (int n, int k) { int mask = 1; for (int i = 1; i < k; ++i) mask = mask << 1; return ~n & mask; }
