WebJun 21, 2024 · Permutations are the possible ways we could order, or arrange, a set. Given a set of n elements, there are n! (n factorial) possible permutations, where n is the number of elements in the set. For this problem we have three elements in our array of integers, so there are 1 * 2 * 3 = 6 possible permutations. WebThe description of the test cases follows. The first line of each test case contains a single integer n ( 1 ≤ n ≤ 10 5) — the size of the array. The second line contains n distinct integers a 1, a 2, …, a n ( 1 ≤ a i ≤ n ), the initial permutation a. It's guaranteed that the sum of n over all test cases does not exceed 2 ⋅ 10 5.
