WebNov 25, 2024 · Solution 1: Brute Force Intuition: The brute force solution is to generate all possible subarrays. For each generated subarray we get the respective XOR and then check if this XOR is equal to B. If it is then we increment the count. In the end, we will get the count of all possible subarrays that have XOR equal to B. Approach: WebSep 2, 2024 · A Computer Science portal for geeks.
