Problem Description
There is a matrix M that has n rows and m columns (1≤n≤1000,1≤m≤1000).Then we perform q(1≤q≤100,000) operations:
1 x y: Swap row x and row y (1≤x,y≤n);
2 x y: Swap column x and column y (1≤x,y≤m);
3 x y: Add y to all elements in row x (1≤x≤n,1≤y≤10,000);
4 x y: Add y to all elements in column x (1≤x≤m,1≤y≤10,000);
Input
There are multiple test cases. The first line of input contains an integer T(1≤T≤20) indicating the number of test cases. For each test case:
The first line contains three integers n, m and q.
The following n lines describe the matrix M.(1≤Mi,j≤10,000) for all (1≤i≤n,1≤j≤m).
The following q lines contains three integers a(1≤a≤4), x and y.
Output
For each test case, output the matrix M after all q operations.
