    writer:pprp

    通过这个题温习了一下刚学的LCS

    代码如下:

    /*
    @theme:hdu1159
    @writer:pprp
    @begin:17:01
    @end:17:06
    @declare:LCS的裸题,温习一下
    @error:从1开始读入的话,用strlen也要从1开始测才可以
    @date:2017/9/2
    */
    
    #include <bits/stdc++.h>
    
    using namespace std;
    
    char s1[1010],s2[1010];
    int dp[1010][1010];
    int main()
    {
    
        //freopen("in.txt","r",stdin);
        while(~scanf("%s%s",s1+1,s2+1))
        {
            memset(dp,0,sizeof(dp));
            int n = strlen(s1+1);
            int m = strlen(s2+1);
    
            for(int i = 1; i <= n ;i++)
            {
                for(int j = 1; j <= m ; j++)
                {
                    if(s1[i] == s2[j])
                        dp[i][j] = dp[i-1][j-1] + 1;
                    else
                        dp[i][j] = max(dp[i-1][j],dp[i][j-1]);
                }
            }
            cout << dp[n][m] << endl;
        }
    
        return 0;
    }
