406019: GYM102219 B SpongeBob SquarePants

Sponge Bob, the famous cartoon character can only wear square shape pants. Squares shape can be described in geometry as having 4 right angles, just like rectangles. But a square is a special case of rectangle where its width and height are the same.

You are given the width and the height of a 4 right angled shape and need to figure out if it is a square or a rectangle for Sponge Bob. He will get all the square ones as his new pants for the coming Eidul Fitri.

The first line contains $$$T$$$, the number of test cases. For each test case there is a line with two integers (1 ≤ $$$w, h$$$ ≤ 1,000,000) representing width and height, respectively.

For each test case, print one line consists of $$$'YES'$$$ (without quotes) if the shape is a square and good for Sponge Bob's pants, otherwise print $$$'NO'$$$ (without quotes) if it is a rectangle and not suitable to be Sponge Bob's pants.
