Vlad Building Beautiful Array

Vlad was given an array aa of nn positive integers. Now he wants to build a beautiful array bb of length nn from it.

Vlad considers an array beautiful if all the numbers in it are positive and have the same parity. That is, all numbers in the beautiful array are greater than zero and are either all even or all odd.

To build the array bb, Vlad can assign each bib_i either the value aia_i or aiaja_i - a_j, where any jj from 11 to nn can be chosen.

To avoid trying to do the impossible, Vlad asks you to determine whether it is possible to build a beautiful array bb of length nn using his array aa.

Input

The first line of input contains an integer tt (1t1041 \le t \le 10^4) — the number of test cases.

Then follow the descriptions of the test cases.

The first line of each case contains a single integer nn (1n21051 \le n \le 2 \cdot 10^5) — the length of the array aa.

The second line of each case contains nn positive integers a1,a2,,ana_1, a_2, \dots, a_n (1ai1091 \le a_i \le 10^9) — the elements of the array aa.

It is guaranteed that the sum of nn over all cases does not exceed 21052 \cdot 10^5.

Output

Output tt strings, each of which is the answer to the corresponding test case. As the answer, output "YES" if Vlad can build a beautiful array bb, and "NO" otherwise.

You can output the answer in any case (for example, the strings "yEs", "yes", "Yes" and "YES" will be recognized as a positive answer).
