CF1851B.Parity Sort

You have an array of integers $a$ of length $n$ . You can apply the following operation to the given array:

• Swap two elements $a_i$ and $a_j$ such that $i \neq j$ , $a_i$ and $a_j$ are either both even or both odd.

Determine whether it is possible to sort the array in non-decreasing order by performing the operation any number of times (possibly zero).

For example, let $a$ = [ $7, 10, 1, 3, 2$ ]. Then we can perform $3$ operations to sort the array:

1. Swap $a_3 = 1$ and $a_1 = 7$ , since $1$ and $7$ are odd. We get $a$ = [ $1, 10, 7, 3, 2$ ];
2. Swap $a_2 = 10$ and $a_5 = 2$ , since $10$ and $2$ are even. We get $a$ = [ $1, 2, 7, 3, 10$ ];
3. Swap $a_4 = 3$ and $a_3 = 7$ , since $3$ and $7$ are odd. We get $a$ = [ $1, 2, 3, 7, 10$ ].

The first line of input data contains a single integer $t$ ( $1 \le t \le 10^4$ ) — the number of test cases.

The description of the test cases follows.

The first line of each test case contains one integer $n$ ( $1 \le n \le 2 \cdot 10^5$ ) — the length of array $a$ .

The second line of each test case contains exactly $n$ positive integers $a_1, a_2, \dots, a_n$ ( $1 \le a_i \le 10^9$ ) — the elements of array $a$ .

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10^5$ .

For each test case, output on a separate line:

• YES if the array can be sorted by applying the operation to it some number of times;
• NO otherwise.

You can output YES and NO in any case (for example, strings yEs, yes, Yes and YES will be recognized as positive response).

The first test case is explained in the problem statement.
