#458 Three Permutations and Queries

Statement

Statement language

Three permutations $p,q,r$ of length $N$ are given. Each permutation contains every integer from $1$ to $N$ exactly once.

A permutation $a$ of length $N$ is called good if it satisfies the following condition.

For every pair of distinct integers $x,y$ , if $x$ appears before $y$ in $a$ , then $x$ also appears before $y$ in at least two of .

There are $M$ queries. Each query swaps two adjacent elements in one of the three permutations. The changes made by previous queries remain in effect.

Immediately after each query, determine whether a good permutation exists for the current $p,q,r$ .

Input

The input is given from Standard Input in the following format:

$T$ $\mathrm{case}_1$ $\mathrm{case}_2$

Output

For each query of each test case, print YES if a good permutation exists immediately after the query, and print NO otherwise. Print one answer per line.

Constraints

$1 \le T \le 100\,000$ .
$2 \le N \le 200\,000$ .
$1 \leq M$ .
