Queue-jumpersTime Limit: 2000/1000 MS (Java/Others) Memory Limit: 32768/32768 K (Java/Others)Total Submission(s): 5404 Accepted Submission(s): 1520 Problem Description Ponyo and Garfield are waiting outside the box-office for their favorite movie. Because queuing is so boring, that they want to play a game to kill the time. The game is called ¡°Queue-jumpers¡±. Suppose that there are N people numbered from 1 to N stand in a line initially. Each time you should simulate one of the following operations: 1. Top x :Take person x to the front of the queue 2. Query x: calculate the current position of person x 3. Rank x: calculate the current person at position x Where x is in [1, N]. Ponyo is so clever that she plays the game very well while Garfield has no idea. Garfield is now turning to you for help. Input In the first line there is an integer T, indicates the number of test cases.(T<=50) In each case, the first line contains two integers N(1<=N<=10^8), Q(1<=Q<=10^5). Then there are Q lines, each line contain an operation as said above. Output For each test case, output ¡°Case d:¡° at first line where d is the case number counted from one, then for each ¡°Query x¡± operation ,output the current position of person x at a line, for each ¡°Rank x¡± operation, output the current person at position x at a line.
