Sakurako's Exam
Description
Today, Sakurako has a math exam. The teacher gave the array, consisting of $a$ ones and $b$ twos.
In an array, Sakurako must place either a '+' or a '-' in front of each element so that the sum of all elements in the array equals $0$.
Sakurako is not sure if it is possible to solve this problem, so determine whether there is a way to assign signs such that the sum of all elements in the array equals $0$.
The first line contains a single integer $t$ ($1\le t\le 100$) — the number of test cases.
The only line of each test case contains two integers $a$ and $b$ ($0\le a,b<10$) — the number of '1's and the number of '2's in the array.
For each test case, output "Yes" if you can make the sum of the entire array equal to $0$, and "No" otherwise.
You can output each letter in any case (lowercase or uppercase). For example, the strings "yEs", "yes", "Yes", and "YES" will be accepted as a positive answer.

Note
- $a=0$, $b=1$: This means the array is $[2]$ — it is impossible to add the signs '+' or '-' to get $0$ as a result;
- $a=0$, $b=3$: This means the array is $[2, 2, 2]$ — it is impossible to add the signs '+' or '-' to get $0$ as a result;
- $a=2$, $b=0$: This means the array is $[1, 1]$ — it is possible to add the signs '+' or '-' to get $0$ as a result ($+1-1=0$);
- $a=2$, $b=3$: This means the array is $[1, 1, 2, 2, 2]$ — it is possible to add the signs '+' or '-' to get $0$ as a result ($+1+1-2-2+2=0$);
