A. Prime Subtraction time limit per test2 seconds memory limit per test256 megabytes inputstandard input outputstandard output You are given two integers x and y (it is guaranteed that x>y). You may choose any prime integer p and subtract it any number of times from x. Is it possible to make x equal to y? Recall that a prime number is a positive integer that has exactly two positive divisors: 1 and this integer itself. The sequence of prime numbers starts with 2, 3, 5, 7, 11. Your program should solve t independent test cases. Input The first line contains one integer t (1≤t≤1000) — the number
