MATNUM - Divisibility Test
Problem statement is simple and straight forward. You will be given a non-negative integer P of length N and you need to check whether it's divisible by Q?
Integer P will be given in its decimal representation with P0 as leftmost digit and P1 as second digit from left!
Rest of the digit can be generated from the formula:
Pi = (4*Pi-1 + Pi-2) modulo Q for 2 <= i <= N-1
Input
The first line contains one integer T - denoting the number of test cases.
T lines follow each containing four integers P0, P1, Q and N!
Output
For each testcase output YES if the corresponding integer is divisible by Q and NO otherwise.
Constraints
- T <= 100000
- 0 < P0, P1, Q < 10
- 0 < N <= 1018
Example
Input: 4 1 4 2 2 1 4 2 1 4 2 3 2 3 4 7 3 Output: YES NO YES NO
Explanation
Value of P is 14, 1, 42, 345 in respective cases !
