一直向前搜..做法有点像模拟.但是要用到出队入队,有点像搜索. 代码: #include <iostream> #include <cstdio> #include <cstring> #include <cmath> #include <algorithm> #include <queue> using namespace std; #define N 100003 struct node { int p,d; bool opera…

还是优先队列 #include<iostream> #include<cstdio> #include<cstring> #include<queue> using namespace std; #define maxn 100010 struct Node { int x,y,id; friend bool operator < (Node a,Node b) { if(a.x != b.x) return a.x > b.x; else if…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1896 题目意思:给出 n 块石头的初始位置和能到达的距离.对于第奇数次遇到的石头才抛掷,偶数次的就忽略.问最多能扔到多远.如果有多颗石头在一个位置,距离小的那个标记为先遇到的. 所以先解说一下第二个测试案例: 2 1  5 6  6 在6这个位置的时候,由于5比6小,所以规定1(5)这个点是先遇上的,是偶数次遇到,所以忽略. 用优先队列做,位置近的优先级越高,如果位置相同,距离短的优先级越高. #i…

http://acm.hdu.edu.cn/showproblem.php?pid=1509 裸的优先队列的应用,输入PUT的时候输入名字,值和优先值进队列,输入GRT的时候输出优先值小的名字和对应的值 注意的是优先级一样的时候输出顺序在前的 #include<cstdio> #include<cstring> #include<queue> using namespace std; struct point { int val,odr,num; ]; bool ope…
