Problem Description
There is a matrix M技术分享 that has n技术分享 rows and m技术分享 columns (1≤n≤1000,1≤m≤1000)技术分享.Then we perform q(1≤q≤100,000)技术分享 operations:

1 x y: Swap row x and row y (1≤x,y≤n)技术分享;

2 x y: Swap column x and column y (1≤x,y≤m)技术分享;

3 x y: Add y to all elements in row x (1≤x≤n,1≤y≤10,000)技术分享;

4 x y: Add y to all elements in column x (1≤x≤m,1≤y≤10,000)技术分享;
 

Input
There are multiple test cases. The first line of input contains an integer T(1≤T≤20)技术分享 indicating the number of test cases. For each test case:

The first line contains three integers n技术分享, m技术分享 and q技术分享.
The following n技术分享 lines describe the matrix M.(1≤M技术分享i,j技术分享≤10,000)技术分享 for all (1≤i≤n,1≤j≤m)技术分享.
The following q技术分享 lines contains three integers a(1≤a≤4)技术分享, x技术分享 and y技术分享.
 

Output
For each test case, output the matrix M技术分享 after all q技术分享 operations.
 

Sample Input
2 3 4 2 1 2 3 4 2 3 4 5 3 4 5 6 1 1 2 3 1 10 2 2 2 1 10 10 1 1 1 2 2 1 2
 

Sample Output
12 13 14 15 1 2 3 4 3 4 5 6 1 10 10 1
Hint
Recommand to use scanf and printf
 


中文题面:BC Round #81 (div.2)1002  


代码如下:

#include<cstdio>
#include<cstring>
#include<algorithm>
using namespace std;
int map[1010][1010];
int row[1010],col[1010];
int hx[1010],hy[1010]; 
int main()
{
	int t,n,m,q,i,j,a,x,y;
	scanf("%d",&t);
	while(t--)
	{
		scanf("%d%d%d",&n,&m,&q);
		for(i=1;i<=n;++i)
		{
			for(j=1;j<=m;++j)
			{
				scanf("%d",&map[i][j]);
				row[i]=i; 
				hx[i]=0;
			}
		}
		for(j=1;j<=m;++j)
		{
			col[j]=j;
			hy[j]=0;
		}
		while(q--)
		{
			scanf("%d%d%d",&a,&x,&y);
			if(a==1)
				swap(row[x],row[y]);
			else if(a==2)
				swap(col[x],col[y]);
			else if(a==3)
				hx[row[x]]+=y;
			else 
				hy[col[x]]+=y; 
				
		}
		for(i=1;i<=n;++i)
		{
			for(j=1;j<=m;++j)
			{
				if(j==m)
					printf("%d\n",map[row[i]][col[j]]+hx[row[i]]+hy[col[j]]);
				else
					printf("%d ",map[row[i]][col[j]]+hx[row[i]]+hy[col[j]]);
			}
		} 
	} 
	return 0;
}
