题目描述
You are given one integer n ( n>1 ).
Recall that a permutation of length n is an array consisting of n distinct integers from 1 to n in arbitrary order. For example, [2,3,1,5,4] is a permutation of length 5 , but [1,2,2] is not a permutation ( 2 appears twice in the array) and [1,3,4] is also not a permutation ( n=3 but there is 4 in the array).
Your task is to find a permutation p of length n that there is no index i ( 1≤i≤n ) such that pi=i (so, for all i from 1 to n the condition pi=i should be satisfied).
You have to answer t independent test cases.
If there are several answers, you can print any. It can be proven that the answer exists for each n>1 .
输入格式
The first line of the input contains one integer t ( 1≤t≤100 ) — the number of test cases. Then t test cases follow.
The only line of the test case contains one integer n ( 2≤n≤100 ) — the length of the permutation you have to find.
输出格式
For each test case, print n distinct integers p1,p2,…,pn — a permutation that there is no index i ( 1≤i≤n ) such that pi=i (so, for all i from 1 to n the condition pi=i should be satisfied).
If there are several answers, you can print any. It can be proven that the answer exists for each n>1 .
