Thief trying to escape

A thief trying to escape from a jail has to cross N walls each with varying heights. He climbs X feet every time. But, due to the slippery nature of those walls, every times he slips back by Y feet. Now the task is to calculate the total number of jumps required to cross all walls and escape from the jail.

Input: The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. Each test case contains two space separated integers X, Y, N. Then in the next line are N space separated values denoting the heights ( Ht[] ) of the walls.

Output: For each test case in a new line print the total number of jumps.

Constraints: 1<=T<=100 1<= N, X, Y <=100 1<= Ht[] <=1000

Example: Input: 2 10 1 1 5 4 1 5 6 9 11 4 5

Output: 1 12
