CF1692D The Clock
Description
Victor has a [24-hour clock](https://en.wikipedia.org/wiki/24-hour_clock) that shows the time in the format "HH:MM" (00 $ \le $ HH $ \le $ 23, 00 $ \le $ MM $ \le $ 59). He looks at the clock every $ x $ minutes, and the clock is currently showing time $ s $ .
How many different palindromes will Victor see in total after looking at the clock every $ x $ minutes, the first time being at time $ s $ ?
For example, if the clock starts out as 03:12 and Victor looks at the clock every $ 360 $ minutes (i.e. every $ 6 $ hours), then he will see the times 03:12, 09:12, 15:12, 21:12, 03:12, and the times will continue to repeat. Here the time 21:12 is the only palindrome he will ever see, so the answer is $ 1 $ .
A palindrome is a string that reads the same backward as forward. For example, the times 12:21, 05:50, 11:11 are palindromes but 13:13, 22:10, 02:22 are not.
Input Format
The first line of the input contains an integer $ t $ ( $ 1 \leq t \leq 100 $ ) — the number of test cases. The description of each test case follows.
The only line of each test case contains a string $ s $ of length $ 5 $ with the format "HH:MM" where "HH" is from "00" to "23" and "MM" is from "00" to "59" (both "HH" and "MM" have exactly two digits) and an integer $ x $ ( $ 1 \leq x \leq 1440 $ ) — the number of minutes Victor takes to look again at the clock.
Output Format
For each test case, output a single integer — the number of different palindromes Victor will see if he looks at the clock every $ x $ minutes starting from time $ s $ .
Explanation/Hint
The first test case is explained in the statement.
