HackerRank ‘Flipping Bits’ Solution - Martin Kysel
Webx1.34 faster than second solution: import numpy as np def reverse_bits_faster(x): x = np.array(x) bits_num = x.dtype.itemsize * 8 # because bitwise operations may change … 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; } in what city was the swing era most prevalent

WebFeb 26, 2024 · 1) Using Loops: By iterating each and every bit we can change the bit 1 to bit 0 and vice-versa. Python3 bit_s = '1010' inverse_s = '' for i in bit_s: if i == '0': inverse_s += '1' else: inverse_s += '0' print("Inversed string is ", inverse_s) Output: Inversed string is 0101 Time complexity: O (n), where n is the length of the input string bit_s. WebFlip Bits. Given an array A [] consisting of 0’s and 1’s. A flip operation is one in which you turn 1 into 0 and a 0 into 1. You have to do at most one “Flip” operation of any subarray. Formally, select a range (l, r) in the array A [], such that (0 ≤ l ≤ r < n) holds and flip the elements in this range to get the maximum ones in ...
