Description

Input

The first line contains an integer $t$ ($1 \le t \le 1000$) — the number of test cases.

Each test case begins with a line containing an integer $n$ ($2 \le n \le 50$) — the length of the array $a$.

The next line contains $n$ integers $a_1,a_2, \dots, a_n$ ($1 \le a_i \le 50$) — the elements of the array $a$.

Output

For each test case, output "YES" (without quotes) if it is possible to color the array in two colors in such a way that the sums of the elements of both colors have the same parity and each color has at least one element colored, and "NO" otherwise.

You can output "Yes" and "No" in any case (for example, the strings "yES", "yes", and "Yes" will be recognized as correct answers).

Note

The first sample is described in the statement.

In the second sample, there are only two colorings $[\color{blue}{4},\color{red}{7}]$ and $[\color{red}{4},\color{blue}{7}]$ , but in both cases the parity of sums is different.

In the third sample, you can color $[\color{blue}{3},\color{blue}{9},\color{red}{8}]$ and $12$ and $8$ are both even.
