B'Karen is getting ready for a new school day! It is currently hh:mm, given in a 24-hour format. As you know, Karen loves palindromes, and she believes that it is good luck to wake up when the time is a palindrome. What is the minimum number of minutes she should sleep, such that, when she wakes up, the time is a palindrome? Remember that a palindrome is a string that reads the same forwards and backwards. For instance, 05:39 is not a palindrome, because 05:39 backwards is 93:50. On the other hand, 05:50 is a palindrome, because 05:50 backwards is 05:50. The first and only line of input contains a single string in the format hh:mm (00 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89 hh xe2 x80 x89 xe2 x89 xa4 xe2 x80 x8923, 00 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89 mm xe2 x80 x89 xe2 x89 xa4 xe2 x80 x8959). Output a single integer on a line by itself, the minimum number of minutes she should sleep, such that, when she wakes up, the time is a palindrome. In the first test case, the minimum number of minutes Karen should sleep for is 11. She can wake up at 05:50, when the time is a palindrome. In the second test case, Karen can wake up immediately, as the current time, 13:31, is already a palindrome. In the third test case, the minimum number of minutes Karen should sleep for is 1 minute. She can wake up at 00:00, when the time is a palindrome. '...
