思路:将数据存在二维数组中,每次查找纵坐标比该坐标值大,横坐标比其小的,即右上角的;
#include<stdio.h>
#include<string.h>
__int64 c[1001][1001];
__int64 result;
__int64 kk;
int main()
{
	int b,i,j,ii,p;
	int n,m,k,x,y;
	scanf("%d",&b);
	for(ii=0;ii<b;ii++)
	{
		for(i=0;i<1001;i++)
		{
			for(j=0;j<1001;j++)
				c[i][j]=0;
		}
		scanf("%d%d%d",&n,&m,&k);			
		result=0;
		for(j=0;j<k;j++)
		{
			scanf("%d%d",&x,&y);		
			c[x][y]++;			
		}		
		result=0;
		for(i=1;i<=n;i++)
		{
			kk=0;
			for(j=m;j>0;j--)
			{
				if(c[i][j]>0)
				{					
					result+=c[i-1][j]*c[i][j];					
					p=kk;
					kk+=c[i][j];	
					c[i][j]=p+c[i-1][j];					
				}
				else c[i][j]=kk+c[i-1][j];
			}
		}
		printf("Text case %d: %I64d\n",ii+1,result);		
	}
	return 1;
}
