## 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

## William has two numbers aa and bb initially both equal to zero. William mastered performing three different operations with them quickly. Before performing each operation some positive integer kk is picked, which is then used to perform one of the following operations: (note, that for each operation you can choose a new positive integer kk) 100% correct solution
