CF1380A.Three Indices
Three Indices
You are given a permutation . Recall that sequence of integers is called a permutation if it contains all integers from to exactly once.
Find three indices , and such that:
- ;
- and .
Or say that there are no such indices.
Input
The first line contains a single integer () — the number of test cases.
Next lines contain test cases — two lines per test case. The first line of each test case contains the single integer () — the length of the permutation .
The second line contains integers (; if ) — the permutation .
Output
For each test case:
- if there are such indices , and , print
YES(case insensitive) and the indices themselves; - if there are no such indices, print
NO(case insensitive).
If there are multiple valid triples of indices, print any of them.
