WebApr 19, 2024 · BITWISE AND of all subarrays of given Integer array. The question is incomplete. No one will ask you to find the bitwise and of all subarrays - Since the number of subarrays for an array of size N will be \frac{N\times(N+1)}{2}. They could ask you a little more, like find the number of distinct values or bitwise-or of bitwise-and of all subarrays.

Efficient Solution: For the sake of better understanding, let’s assume that any bit of an element is represented by the variable ‘i’ and the variable ‘sum’ is used to store the final sum. The code is assuming int are 32 bits and numbers are never negative.
WebFeb 7, 2024 · For each pair, check if its bitwise AND(&) is less than the bitwise XOR(^) of that pair or not. If found to be true, then increment the count of pairs by 1. Finally, print the count of such pairs obtained. Time Complexity: O(N 2) Auxiliary Space: O(1) Efficient approach: To optimize the above approach, follow the properties of the bitwise ...
csm areas of special emphasisWebApr 12, 2024 · The bitwise & function on subarrays is weakly-monotonic with respect to subarray inclusion. Therefore the basic approach of increasing the right pointer when the &-value is too large, and increasing the left pointer when the &-value is too small, will cause our sliding window to equal an optimal sliding window at some point. csmari announcementWebSep 2, 2024 · Hi, everyone!
