There is an array with n integers, but the values are hidden to us. Our goal is to partition the elements into groups based on their values – elements in the same group should have the same value, while elements in different groups have different values. The values are hidden to us so you cannot directly call for a value, like Arr[i]. However, we can probe the array by calling the function query(). The function takes a subset of elements as inputs and returns the number of unique integers in this subset. Design an algorithm to partition these n elements in O(nlog n) queries. (query() is called O(nlogn) times) 4.
