We have a very famous and popular fellow in our problem- setters’ panel. He is so famous that his name is immaterial. Some of his admirers have recently given him the nickname ’Emoogle’. Let’s stick to that name in our discussion for now. Being such a kind, friendly and generous person as he is, Emoogle is often known to give treats to the other problemsetters. Some times, there is a strange rumor in the air that his treats are mostly due to the fact that, if he is not sparing enough for those treats, ’problems’ are likely to be created. But let’s not pay heed to such nonsense! Now, there is another word in the air that this remark- able man is going to get married soon. To observe this spe- cial occasion with proper respect, his fellow troublemakers have decided to compile a book named ’99 reasons why Emoogle should give us a treat’. Every single reason mentioned in this book is denoted by a number. For example, Emoogle should give us a treat because
2/2 Input There are around 75 test cases in the input file. Each test case describes a series of events. A test case starts with an integer N (1 ≤ N ≤ 1000) denoting the number of events in this test case. This integer is followed by a line with N integers, each describing an event. These integers have values between 0 and 99 (inclusive). A value between 1 and 99 means a reason for Emoogle’s giving a treat has occurred while a 0 means he has given a treat. The end of input will be denoted by a case with N = 0. This case should not be processed. Output For each test case, print a line in the format, ‘Case X: Y ’, where X is the case number and Y is the Emoogle Balance for this case. Sample Input 5 34001 4 2000 7 1234500 0 Sample Output Case 1: 1 Case 2: -2 Case 3: 3
