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.

@narendra pal: yes....as it is given x,y can be negative and "non-negative" integers , zero includes in 2nd category... |

can zero be the value of x or y ?? |

Good one, I went in completely wrong direction with prime factorizing a,b and c and wasted quite a lot time. |

Don't forget to put space betwen ':' and 'Yes' or 'No' . Costed me a hell of nervs.... |
