Currently, his assets are worth A billion dollars and have no liabilities. He aims to increase his assets by X billion dollars per year. Also, all the richest people in Chefland are not planning to grow and maintain their current worth. To be the richest person in Chefland, he needs to be worth at least B billion dollars. How many years will it take Chef to reach his goal if his value increases by X billion dollars each year? Input The first line contains an integer T, the number of test cases. Then the test cases follow. Each test case contains a single line of input, three integers A, B, X. Output For each test case, output in a single line the answer to the problem. Constraints 1 ≤ T ≤ 21 000 100 ≤ A less than B ≤ 200 1 ≤ X ≤ 50 X divides B − A Subtasks Subtask #1 (100 points): Original constraints Sample Input 3 100 200 10 111 199 11 190 200 10 Sample Output 10 8 1 Explanation Test Case 1: Chef needs to increase his worth by 200−100=100 billion dollars and his increment per year being 10 billion dollars, so it will take him 10010=10 years to do so. Test Case 2: Chef needs to increase his worth by 199−111=88 billion dollars and his increment per year being 11 billion dollars, so it will take him 8811=8 years to do so. Test Case 3: Chef needs to increase his worth by 200−190=10 billion dollars and his increment per year being 10 billion dollars, so it will take him 1010=1 year to do so.
