( 282 ) D Inverse Inversions PROGRAMMING binary search brute force data structures

B"You were playing with permutation p of length n , but you lost it in Blair, Alabama! Luckily, you remember some information about the permutation. More specifically, you remember an array b of length n , where b_i is the number of indices j such that j < i and p_j > p_i . You have the array b , and you want to find the permutation p . However, your memory isn't perfect, and you constantly change the values of b as you learn more. For the next q seconds, one of the following things happen: Answer the queries, so you can remember the array! The first line contains a single integer n ( 1 <= q n <= q 10^5 ) -- the size of permutation. The second line contains n integers b_1, b_2 ldots, b_n ( 0 <= q b_i < i ) -- your initial memory of the array b . The third line contains a single integer q ( 1 <= q q <= q 10^5 ) -- the number of queries. The next q lines contain the queries, each with one of the following formats: It is guaranteed that there's at least one query of type 2 . For each query of type 2 , print one integer -- the answer to the query. For the first sample, there's initially only one possible permutation that satisfies the constraints: [1, 2, 3] , as it must have 0 inversions. After the query of type 1 , the array b is [0, 1, 0] . The only permutation p that produces this array is [2, 1, 3] . With this permutation, b_2 is equal to 1 as p_1 > p_2 . "...
