Bitwise xor subsequence
WebFeb 7, 2024 · Time Complexity: O(N) Auxiliary Space: O(1) Method 2 : Bitwise and is greater than bitwise xor if and only if most significant bit is equal. Create a bits[] array of size 32 (max no of bits); Initialize ans to 0.; We will traverse the array from the start and for each number, Find its most significant bit and say it is j. WebA sequence a is a subsequence of a sequence b if a can be obtained from b by the deletion of several (possibly, zero or all) elements. For example, for n = 15, k = 6, x = 7, the following scheme is valid: where ⊕ represents the bitwise XOR operation. [ 7], 7 = 7. The following scheme is invalid, since 3 appears twice, and 1, 2 do not appear:
