Problem Description
One day, a useless calculator was being built by Kuros. Let's assume that number X is showed on the screen of calculator. At first, X = 1. This calculator only supports two types of operation. 1. multiply X with a number. 2. divide X with a number which was multiplied before. After each operation, please output the number X modulo M.
Input
The first line is an integer T( 1≤T≤10), indicating the number of test cases.For each test case, the first line are two integers Q and M. Q is the number of operations and M is described above. (1≤Q≤105,1≤M≤109)The next Q lines, each line starts with an integer x indicating the type of operation.if x is 1, an integer y is given, indicating the number to multiply. (0<y≤109)if x is 2, an integer n is given. The calculator will divide the number which is multiplied in the nth operation. (the nth operation must be a type 1 operation.)It's guaranteed that in type 2 operation, there won't be two same n.
Output
For each test case, the first line, please output "Case #x:" and x is the id of the test cases starting from 1. Then Q lines follow, each line please output an answer showed by the calculator.
Sample Input
1 10 1000000000 1 2 2 1 1 2 1 10 2 3 2 4 1 6 1 7 1 12 2 7
Sample Output
Case #1: 2 1 2 20 10 1 6 42 504 84

或者线段树上搞
