Pro.ID22713 TitleCow Line Title链接http://10.20.2.8/oj/exercise/problem?problem_id=22713 AC8 Submit141 Ratio5.67% 时间&空间限制描述The N (1 ≤ N ≤ 20) cows conveniently numbered 1...N are playing yet another one of their crazy games with Farmer John. The cows will arrange themselves in a line and ask Farmer John what their line number is. In return, Farmer John can give them a line number and the cows must rearrange themselves into that line. A line number is assigned by numbering all the permutations of the line in lexicographic order. Consider this example: Farmer John has 5 cows and gives them the line number of 3. The permutations of the line in ascending lexicographic order: 1st: 1 2 3 4 5 Therefore, the cows will line themselves in the cow line 1 2 4 3 5. The cows, in return, line themselves in the configuration "1 2 5 3 4" and ask Farmer John what their line number is. Continuing with the list: 4th : 1 2 4 5 3 Farmer John can see the answer here is 5 Farmer John and the cows would like your help to play their game. They have K (1 ≤ K ≤ 10,000) queries that they need help with. Query i has two parts: Ci will be the command, which is either 'P' or 'Q'. If Ci is 'P', then the second part of the query will be one integer Ai ( 1 ≤ Ai ≤ N! ), which is a line number. This is Farmer John challenging the cows to line up in the correct cow line. If Ci is 'Q', then the second part of the query will be N distinct integers Bij (1 ≤ Bij ≤ N). This will denote a cow line. These are the cows challenging Farmer John to find their line number. 输入Multiple test cases. For each case: Line 1: Two space-separated integers: N and K Lines 2..2×K+1: Line 2×i and 2×i+1 will contain a single query. Line 2×i will contain just one character: 'Q' if the cows are lining up and asking Farmer John for their line number or 'P' if Farmer John gives the cows a line number. If the line 2×i is 'Q', then line 2×i+1 will contain N space-separated integers Bij which represent the cow line. If the line 2×i is 'P', then line 2×i+1 will contain a single integer Ai which is the line number to solve for. 输出Description The N (1 ≤ N ≤ 20) cows conveniently numbered 1...N are playing yet another one of their crazy games with Farmer John.

Input Multiple test cases. For each case: Line 1: Two space-separated integers: N and K Lines 2..2×K+1: Line 2×i and 2×i+1 will contain a single query. Line 2×i will contain just one character: 'Q' if the cows are lining up and asking Farmer John for their line number or 'P' if Farmer John gives the cows a line number. If the line 2×i is 'Q', then line 2×i+1 will contain N space-separated integers Bij which represent the cow line. If the line 2×i is 'P', then line 2×i+1 will contain a single integer Ai which is the line number to solve for. Output For each case, output : Lines 1..K: Line i will contain the answer to query i. If line 2×i of the input was 'Q', then this line will contain a single integer, which is the line number of the cow line in line 2×i+1. If line 2×i of the input was 'P', then this line will contain N space separated integers giving the cow line of the number in line 2×i+1. Output a blank line after each case.
