题目:http://poj.org/problem?id=1472 这个题目是分到“模拟题”一类的,我觉得模拟的成分比较少,主要考察编程能力.独立写完这个题特别兴奋...所以我必须好好说一说,独家哦... 题意是计算一段伪代码的时间复杂度,整体代码夹在“BEGIN”和“END”之间,中间有很多循环语句,夹在“LOOP X”和“END”之间,表示循环X次.第一眼一看很难下手,其实只要想到一点这个题就非常水了: “BEGIN”语句可以看做”LOOP 1“. 这样的话整个程序的递归结构就明显了,就是L…

题意:就是让你求出时间复杂度. 分析:由于指数最多为10次方,所以可以想到用一个数组保存各个指数的系数,具体看代码实现吧! 代码实现: #include<cstdio> #include<cstring> #include<iostream> #include<algorithm> using namespace std; ][]; ]; int num; struct node{ ]; void init() { memset(sum,,sizeof(su…
Description Too worrying about the house price bubble, poor Mike sold his house and rent an apartment in a 50-floor building several months ago. This building has only one elevator because it is a so called “rotten tail building”. There are always a…
题目链接: http://poj.org/problem?id=2632 题目描述: 有一个B*A的厂库,分布了n个机器人,机器人编号1~n.我们知道刚开始时全部机器人的位置和朝向,我们可以按顺序操控机器人,没有两个机器人可以同时执行命令.如果机器人走到厂库边界,他将碰到墙,如果两个机器人走到同一位置,则表示他们两个相撞.问m个命令内最先发生的碰撞,如果没有碰撞输出“OK”. 解题思路: 由图可知,本题的矩阵与平时的不太一样,所以我们在对厂库进行操作的时候,可以先把厂库顺时针旋转90°,当然,方…
http://poj.org/problem?id=2014 嘻嘻2014要到啦,于是去做Prob.ID 为2014的题~~~~祝大家新年快乐~~ 题目大意: 给你一个最大宽度的矩形,要求把小矩形排放在内,只有当这一行小矩形的宽度超过最大宽度后,才能放入下一行. 求最后放好后的宽度和高度. (具体看题目吧,好像表述得不太清楚) 思路: 就按题目给定矩形的顺序直接来模拟就好了.. 不用旋转不用排序各种不要... #include<cstdio> #include<algorithm>…
题目链接:http://poj.org/problem?id=2632 先话说昨天顺利1Y之后,直到今天下午才再出题 TAT,真是刷题计划深似海,从此AC是路人- - 本来2632是道略微恶心点的模拟,但毕竟是模拟,一般模拟都是仅仅要演示样例过了基本就AC了.但这个题非常特殊 我開始的时候一直跑不出測试演示样例.才发现题目中的插图和我构想的坐标系是不一样的(看来还不能轻易忽视掉插图啊) watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvY29kZWh5cG…
