for this sum

why is this code not accepted even though the logic and code gives right answers?
import java.util.Scanner;

class Codechef {
public static void main(String args) {
Scanner read = new Scanner(System.in);

    int t = read.nextInt();
    for (int i = 0; i < t; i++) {
        int a = read.nextInt();
        int b = read.nextInt();

        // Update your code below this line to solve the problem
        while (a < b) {
            if (a % 2 == 0) {
                a = a + 2;
            } else {
                a = a + 1;
            }
        }

        if (a != b) {
            System.out.println("NO");
        } else {
            System.out.println("YES");
        }
    }
}

@padmakshi
may be your code is failing for some edge test cases.
plzz refer the following solution for better understanding

// Solution as follows
import java.util.Scanner;
class Codechef
{
	public static void main (String[] args)
	{
		Scanner read = new Scanner(System.in);
		
		int t = read.nextInt();
		for(int i=0; i<t; i++)
		{
    		int a = read.nextInt();
    		int b = read.nextInt();
    		
    		int diff = b-a;
    		
    		if((b-a)%3 == 0){
    		    System.out.println("YES");
    		}
    		else if((b-a)%3 == 1){
    		    System.out.println("YES");
    		}
    		else{
    		    System.out.println("NO");
    		}
		}
	}
}
