题目大意 计算循环小数的位数,并且按照格式输出 怎么做 一句话攻略算法核心在于a=a%b*10,用第一个数组记录被除数然后用第二个数组来记录a/b的位数.然后用第三个数组记录每一个被除数出现的位置好去寻找循环节的位置. 我的代码(算法还是借鉴) #include <iostream> #include <cstring> using namespace std; int ar[300000]; int re[300000]; int lc[300000]; int main() {…

原题链接:https://vjudge.net/problem/UVA-202 题意:求一个数除以一个数商,如果有重复的数字(循环小数),输出,如果没有,输出前50位. 题解:这个题一开始考虑的是一个一个判,但太麻烦,复杂度太高,于是转化思路,如果是循环小数,那么余数与之前的相同,那么只需要统计余数是否相同,及其所出现的位置 ac代码 #include<iostream>#include<cstdio>#include<cstring>using namespace s…

Repeating Decimals 紫书第3章,这哪是模拟啊,这是数论题啊 [题目链接]Repeating Decimals [题目类型]抽屉原理 &题解: n除以m的余数只能是0~m-1,根据抽屉原则,当计算m+1次时至少存在一个余数相同,即为循环节:存储余数和除数,输出即可. 上面是我查到的,现在让我解释一下: 比如5/43,先是要模拟除法运算,第一步50/43 余7;第二步,70/43 于27... 这样一直取余下去,肯定不会超过43次,就会有余数相同的情况,有相同情况就是找到循环节了.…

给你两个数,问你他们相除是多少,有无限循环就把循环体括号括起来 模拟除法运算 把每一次的被除数记下,当有被除数相同时第一个循环就在他们之间. 要注意50个数之后要省略号...每一次输出之后多打一个回车... #include <iostream> #include <cstring> using namespace std; int a,b; ];//记录该被除数出现的位置 ],num,cnt; void fuc() { memset(flag,,; ) { ) break; fl…

题意:给出几个圆的半径,贴着底下排放在一个长方形里面,求出如何摆放能使长方形底下长度最短. 由于球的个数不会超过8, 所以用全排列一个一个计算底下的长度,然后记录最短就行了. 全排列用next_permutation函数,计算长度时坐标模拟着摆放就行了. 摆放时折腾了不久,一开始一个一个把圆放到最左端,然后和前面摆好的圆比较检查是否会出现两个圆重叠,是的话就把当前圆向右移动到相切的位置.然后判断宽度. 结果发现过不了几个例子,检查了好久,终于发现问题出在初始位置上,如果出现一个特别小的圆放到最左…

状压dp,每个状态可以表示为一个n元组,且上限为8,可以用一个九进制来表示状态.但是这样做用数组开不下,用map离散会T. 而实际上很多九进制数很多都是用不上的.因此类似uva 1601 Morning after holloween的思想,先dfs预处理出所有状态,用map将状态离散, 预处理出算出状态的转移DAG,而不是转移的时候在解码编码判断是否可行,然后一层一层bfs就行了. 附上测试数据 一层一层的bfs转移类似滚动数组,注意初始化(具体问题具体分析,有些问题没有必要做这一步) 一层一…
