# Chef and Difficult Contests Codechef Solution Hello Programmers In this post, you will know how to solve the Chef and Difficult Contests Codechef Solution.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.

### Problem

Oh, these difficult contests… In each contest, there are so many hard tasks Chef cannot solve. However, he knows that he can only become a successful coder if he works hard. Fortunately, he has a problem in mind for training.

You are given two positive integers aa and bb. You may apply the following magical operation any number of times (including zero):

• choose an arbitrary positive integer dd
• perform exactly one of the following actions:

Chef is asking you to find out if it is possible to obtain a=ba=b. Help him!

### Input

• The first line of the input contains a single integer TT denoting the number of test cases. The description of TT test cases follows.
• The first and only line of each test case contains two space-separated integers aa and bb.

### Output

For each test case, print a single line containing the string `"YES"` if it is possible to obtain a=ba=b or `"NO"` if it is impossible.

### Constraints

• 1≤T≤1,0001≤T≤1,000
• 1≤a,b≤1091≤a,b≤109

Subtaks #1 (100 points): original constraints

```1
5 7
```

```YES
```

### Explanation

Example case 1: One possible strategy for Chef is:

• choose d=10d=10, add d−1=9d−1=9 to aa and d=10d=10 to bb; after this operation, a=14a=14 and b=17b=17
• choose d=10d=10, add d=10d=10 to aa and d−1=9d−1=9 to bb; afterwards, a=24a=24 and b=26b=26
• choose d=9d=9, add d=9d=9 to aa and d−1=8d−1=8 to bb; afterwards, a=33a=33 and b=34b=34
