这题解决的算法处理,真的很难想清楚!!尤其是最后的正矩形如何处理.不过终于看懂了 #include<stdio.h> #include<stdlib.h> #include<string.h> #include<limits.h> #define MAX 110 #define min(a,b) ((a)<(b))?(a):(b) char board[MAX][MAX]; int sum[MAX][MAX]; int main(void) { int…

Description We are given a figure consisting of only horizontal and vertical line segments. Our goal is to count the number of all different rectangles formed by these segments. As an example, the number of rectangles in the Figures 1 and 2 are 5 and…

这个题目很好,变形的题目也很多.简单DP. /* 1510 */ #include <cstdio> #include <cstring> #include <cstdlib> #define MAXN 105 char map[MAXN][MAXN]; int dp[MAXN][MAXN]; int min(int a, int b) { return a<b ? a:b; } int main() { int n; int i, j, k, tmp; int…

思路: 友谊赛的时候一直想到了,但是没想出来怎么遍历才能找到所有矩阵,卡住了. 这里讲一下完整思路:我们用一个num[i][j]表示第i行第j列每一列连续的白色格子数量,然后我们定义一个MIN,并且每次都更新MIN的值(因为矩阵高度只和最小的那个有关). 代码: #include<cstdio> #include<vector> #include<stack> #include<queue> #include<cstring> #include&…

作为编码者,美工基础是偏弱的.我们可以参考一些成熟的网页PS教程,提高自身的设计能力.套用一句话,“熟读唐诗三百首,不会作诗也会吟”. 本系列的教程来源于网上的PS教程,都是国外的,全英文的.本人尝试翻译这些优秀的教程.因为翻译能力有限,翻译的细节上还有待推敲,希望广大网友不吝赐教. 约定: 1.本文的软件是Photoshop CS5版本 2.原教程的截图是英文的,本人在重新制作的基础上,重新截了中文版的图 3.原文中有些操作没有给出参数.本人在反复测试的情况下测定了一些参数,以红色的文字显示.…

特征提取的原理.代码等: 如果是白黑白,是减去一个黑的还是2个黑的,网上有不同的说法:应该需要看原论文了. 论文原文 The sum of the pixels which lie within the white rectangles are subtracted from the sum of pixels in the grey rectangles. A three-rectangle feature computes the sum within two outside rectang…
