 Description
Given a sequence of N numbers, initially the numbers are 1, 2, 3…, N in order. And then there are M operations. Each operation belongs to one of two kinds below:
1 a b swap the numbers in position a and position b.
2 a b swap the numbers with value a and b.
You are to do these M operations in order, and then output the result sequence in a line.
 Input
There are several test cases.
The first line an integer T indicating the number of test cases.
For each case, the first line is an integer N (2 <=N<=100) indicating the how many numbers there are in the sequence.
And then a line with an integer M indicating the number of operations. (1 <= M <= 100)
Then M lines following, each containing three numbers: either “1 a b” or “2 a b”, the meaning of which are as the description. (1 <= a, b <= N, a != b)
 Output
For each case, output a single line in the following format:
Case #K: s[1], s[2], … s[N].
K is test case number start from 1, s[i] is the ith number in the result sequence.
 sample input

2 4 3 1 1 3 2 1 4 1 2 3 2 2 1 1 2 1 1 2
 sample output

Case #1: 3 4 2 1 Case #2: 1 2
 hint
For the first case:
Initially, the sequence is {1 2 3 4}
Operation 1, swap the numbers in position 1 and position 3: {3 2 1 4}
Operation 2, swap number 1 the number 4: {3 2 4 1}
Operation 3, swap the numbers in position 2 and position 3: {3 4 2 1}
So, the sesult sequence is {3 4 2 1}
