Array with Odd Sum
Description
You are given an array $a$ consisting of $n$ integers.
In one move, you can choose two indices $1 \le i, j \le n$ such that $i \ne j$ and set $a_i := a_j$. You can perform such moves any number of times (possibly, zero). You can choose different indices in different operations. The operation := is the operation of assignment (i.e. you choose $i$ and $j$ and replace $a_i$ with $a_j$).
Your task is to say if it is possible to obtain an array with an odd (not divisible by $2$) sum of elements.
You have to answer $t$ independent test cases.
The first line of the input contains one integer $t$ ($1 \le t \le 2000$) — the number of test cases.
The next $2t$ lines describe test cases. The first line of the test case contains one integer $n$ ($1 \le n \le 2000$) — the number of elements in $a$. The second line of the test case contains $n$ integers $a_1, a_2, \dots, a_n$ ($1 \le a_i \le 2000$), where $a_i$ is the $i$-th element of $a$.
It is guaranteed that the sum of $n$ over all test cases does not exceed $2000$ ($\sum n \le 2000$).
For each test case, print the answer on it — "YES" (without quotes) if it is possible to obtain the array with an odd sum of elements, and "NO" otherwise.
Input

Output
For each test case, print the answer on it — "YES" (without quotes) if it is possible to obtain the array with an odd sum of elements, and "NO" otherwise.
