Hidden Permutation
There is a hidden permutation a_1, a_2,\dots, a_n of integers 1, 2,\dots, n. Your task is to find this permutation. To do this, you can ask questions: you can choose two indices i and j and you will be told if a_i < a_j. Interaction This is an interactive problem. Your code will interact with the grader using standard input and output. You should start by reading a single integer n: the length
