Posted by lvsheng4 at 2011-07-22 16:21:41 on Problem 1088
#include<iostream>
using namespace std;

#define MAXN 20000

int map[105][105];
int f[105][105];
int x[]={0,0,1,-1};
int y[]={1,-1,0,0};

void dfs(int i,int j)
{
	for(int k=0;k<4;k++)
	{
		if(map[i+x[k]][j+y[k]]>map[i][j] && f[i][j]+1>f[i+x[k]][j+y[k]])
		{
			f[i+x[k]][j+y[k]]=f[i][j]+1;
				dfs(i+x[k],j+y[k]);
		}
			
	}
}

int main()
{
	int r,c,s;
	while(cin>>r>>c)
	{
