The highest output bit is at the end of a chain. Here is a "truth table" using 1's and 0's: You can see that the result of the bitwise operation on two bits will be a 1 if they are different and 0 if they are the same. So, if the input is like n = 6, start = 2, then the output will be 14 because the array will be like [2+2*0, 2+2*1, 2+2*5] = [2,4,6,8,10,12], then XOR of each element present in the array is 14.

Compute the bit-wise XOR of two arrays element-wise. shape (which becomes the shape of the output). Since the maximum number of bits in an integer is log(maximum element in array), the space complexity is O( n log(maximum element in array) ). A mask defines which bit should be present in the answer and which bit is not. Example : Input: Arr = {25, 10, 2, 8, 5, 3} Output: 28 Explanation: The maximum result is 5 ^ 25 = 28 Input: Arr = {1, 2, 3, 4, 5, 6, 7} Output: 7 Explanation: The maximum result is 1 ^ 6 = 7 Recommended Practice Maximum XOR of two numbers in an array Try It!
