( 10374 ) D Zigzags PROGRAMMING brute force data structures dp math two pointers

B"You are given an array a_1, a_2 ... a_n . Calculate the number of tuples (i, j, k, l) such that: The first line contains a single integer t ( 1 <= t <= 100 ) -- the number of test cases. The first line of each test case contains a single integer n ( 4 <= n <= 3000 ) -- the size of the array a . The second line of each test case contains n integers a_1, a_2, ... , a_n ( 1 <= a_i <= n ) -- the array a . It's guaranteed that the sum of n in one test doesn't exceed 3000 . For each test case, print the number of described tuples. In the first test case, for any four indices i < j < k < l are valid, so the answer is the number of tuples. In the second test case, there are 2 valid tuples: "...
