A. [Deque] Depermutаtiоn time limit per test: 1.5 secоnds memоry limit per test: 256 megаbytes You аre given a permutation p, consisting of n distinct integers from 1 to n in arbitrary order. Then, you must create an array q by iteratively picking either the left (first) or right (last) element of p and appending it to q until p is empty. For instance, if p = [1,2,3,4,5] and: you always pick the left element, q = [1,2,3,4,5] you always pick the right element, q = [5,4,3,2,1] you pick the left element twice and then the right element until p is empty, q = [1,2,5,4,3] Your goal is to pick elements in such way that there is no subarray* of q with four or more elements in ascending or descending order. For instance, if p = [1,2,3,4,5], then: q = [1,2,3,4,5] is not a valid answer ([1,2,3,4], [2,3,4,5], and [1,2,3,4,5] are subarrays in ascending order) q = [5,4,3,2,1] is not a valid answer ([5,4,3,2], [4,3,2,1], and [5,4,3,2,1] are subarrays in descending order) q = [1,2,5,4,3] is a valid answer (all subarrays of size 4 or greater are not in ascending or descending order) * A subarray is a sequence of contiguous elements of an array. Input The first line contains a single integer t (1≤t≤104) — the number of test cases. The first line of each test case contains a single integer n (5≤n≤105) — the size of the permutation. The second line of each test case contains n space-separated integers pi (1≤pi≤n) — the elements of the permutation. The sum of n over all test cases doesn't exceed 2⋅105. Output For each test case, you must output a string s of of length n. The i-th character should indicate if the i-th element of q was taken from the left ('L') or right ('R') side of p. A valid answer always exists. If there are multiple solutions, print any of them. HINTS Add p to a deque to have easy access to the first and last elements of p and also to easily remove these elements from p when needed. If q has no subarray of size 4 in ascending or descending order, then it has no subarray of size greater than 4 in ascending or descending order. Think about how can you iteratively use the minimum and maximum between the first and last elements of p to build a valid q.
