// You are given 2 integers - X,Y. You can do one of the following operations multiple times

//   1.Select any other integer Z and increase X by Z and decrease Y by Z OR
//   2.Select any other integer Z and decrease X by Z and increase Y by Z
// After any number of operations - you have to check if X==Y

// Input Format:
// First line will contain T,number of test cases.Then the test cases follow.Each test case contains of a single line of input, two integers,X, Y.

// Output Format:
//  For each test case, if the equality can be achieved - output YES else output NO
