WebSep 2, 2024 · Solution We need to swap two sets of bits. XOR can be used in a similar way as it is used to swap 2 numbers. Following is the algorithm. 1) Move all bits of the first set to the rightmost side set1 = (x >> p1) & ( (1U << n) - 1) Here the expression (1U << n) - 1 gives a number that contains last n bits set and other bits as 0. WebSimply use the bitwise not operator ~. To use the k least significant bits, convert it to the right mask. int flipBits (int n, int k) { int mask = 1; for (int i = 1; i < k; ++i) mask = mask << …

WebSep 27, 2014 · You can perform at most one move on the array :choose any two integers [L,R] and flip all the elements between (and including) the Lth and Rth bits. L and R represent the left most and the right most index of the bits marking the boundaries of the segment which you have decided to flip. WebJun 20, 2024 · On the hackerrank forum itself, there was also a discussion on this topic and I found a nice hand-drawn picture that shows what positions can actually be taken into account (following the lead of the gentleman from YouTube).
