题意:给一个无向图,每条边上都有容量的限制,要求求出给定起点和终点的最大流. 思路:每条无向边就得拆成2条,每条还得有反向边,所以共4条.源点汇点已经给出,所以不用建了.直接在图上跑最大流就可以了. #include <bits/stdc++.h> #define LL long long #define pii pair<int,int> #define INF 0x7f7f7f7f using namespace std; ; ; int s, t; int path[N],…
传送门:https://uva.onlinejudge.org/external/6/p679.pdf 题意:在一颗结点带开关的完全二叉树上扔球,初始时开关为关闭状态,树的深度为D(1 <= D <= 20), 根结点为1(节点从1开始到2D-1),开关为关闭向左子结点走,否则往右子结点走,每到一个结点改变该结点开关状态.问第 I 颗球落在哪. 当 I 是奇数时, 它是往当前结点的左子结点走的第 (I + 1) / 2 颗球; 当 I 是偶数时, 它是往当前结点的右子结点走的第 I / 2 颗…
