题目大意:题目说了一大堆,其实都是废话......让人有些不知所云,其实就是给了一些电厂,和一些消费点,然后里面有一些路线什么的,求出消费点可以最多消费的电量是多少. 输入大意: 分析:懂了题意就是一个模板...还不用拆点什么的,不过输入的时候不太明白为什么scanf("(%d,%d)%d")这种输入不好使了,只得用字符串直接读的. 下面是AC代码. #include<stdio.h> #include<; ; ; s[i]; i++)     {         }…

题目链接:https://vjudge.net/contest/299467#problem/F 这个是一个很简单的题目,但是读入很有意思,通过这个题目,我学会了一种新的读入方式. 一个旧的是(%d,%d)%d  这个,但是这个题目不知道为什么,用不了. 还有一个就是用sscanf   可以看这个博客学习一下 https://blog.csdn.net/yanyanwenmeng/article/details/82753014 #include <cstdio> #include <c…

题意: 2 1 1 2 (0,1)20 (1,0)10 (0)15 (1)20 2 1 1 2 表示 共有2个节点,生产能量的点1个,消耗能量的点1个, 传递能量的通道2条:(0,1)20 (1,0)10 代表(起点,终点)最大传递的能量 (0)15 (产生能量的点)产生的最大能量(1)20 (消费能量的点)消费的最大能量 初学网络流,我想从基础练起:就先用EK算法写一遍 这道题看似很难,但其实只要加一个源点以及汇点,让所有的产生能量的点指向源点,让所有的消费能量的点指向汇点: #include…
