CEQU - Crucial Equation |
Let us see the following equation,
ax + by = c
Given three positive integers a, b and c. You have to determine whether there exists at least one solution for some integers value of x and y where x, y may be negative or non-negative integers.
For example if a = 2, b = 4 and c = 8 then the equation will be 2x + 4y = 8, and hence, for x = 2 and y = 1, there exists a solution.
Let us see another example for a = 3, b = 6 and c = 7, so the equation will become 3x + 6y = 7 and there exists no solution satisfying this equation.
Input
Input starts with an integer T (1 ≤ T ≤ 105) denoting the number of test cases. Each test case contains three integers a, b, and c. (1 ≤ a, b, c ≤ 106).
Output
For each test case of input print the case number and “Yes” if there exists at least one solution, print “No” otherwise.

You don't have to just print "Yes" and "No". Literally, you gotta print Case 1: ... Case 2: ... |
