You are given an array AA consisting of NN integers and an integer XX. Your goal is to have as many equal integers as possible in the array. To achieve this goal, you can do the following operation: Choose an index ii (1≤i≤N)(1≤i≤N) and set Ai=Ai⊕XAi=Ai⊕X, where ⊕⊕ denotes the bitwise xor operation. Find the maximum number of equal integers you can have in the final array and the minimum number of operations to obtain these many equal integers. 100% correct solution

Chef is given an array AA consisting of NN positive integers. Chef shuffles the array AA and creates a new array BB of length NN, where Bi=(Ai+i)mod2Bi=(Ai+i)mod2, for each i(1≤i≤N)i(1≤i≤N). Find the maximum possible sum of integers of the array BB, if Chef shuffles the array AA optimally. 100% correct solution
