Hello Programmers In this post, you will know how to solve the Make A and B equal Codechef Solution. The Problem Code is EQUALISE.
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
Chef has two numbers A and B.
In one operation, Chef can choose either A or B and multiply it by 2.
Determine whether he can make both A and B equal after any number (possibly, zero) of moves.
Input Format
- The first line of input will contain a single integer T, denoting the number of test cases.
- Each test case consists of two space-separated integers A and B.
Output Format
For each test case, output YES if Chef can make both numbers equal, NO otherwise.
Note that the checker is case-insensitive i.e. YES, Yes, yes, yES are all considered same.
Constraints
- 1≤T≤2500
- 1≤A,B≤50
Sample 1:
Input
4 5 20 6 6 12 2 50 20
Output
YES YES NO NO

Explanation:
Test case 1: Chef can multiply A by 2 twice and both A and B will become 20.
Test case 2: Both numbers are already equal.
Test case 3: It can be shown that A and B cannot be made equal.
Test case 4: It can be shown that A and B cannot be made equal.
