题意: 输入两个分数(分子分母各为一个整数中间用'/'分隔),输出它们的四则运算表达式.小数需要用"("和")"括起来,分母为0的话输出"Inf"(输入的分母保证不为0). trick: 测试点2很容易溢出,建议遇到乘法时先化简分数并且不要用相乘小于零来判断异号. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespac…

题目 For two rational numbers, your task is to implement the basic arithmetics, that is, to calculate their sum, diference, product and quotient. Input Specification: Each input file contains one test case, which gives in one line the two rational numb…

输入为两个分数,让你计算+,-,*,\四种结果,并且输出对应的式子,分数要按带分数的格式k a/b输出如果为负数,则带分数两边要有括号如果除数为0,则式子中的结果输出Inf模拟题最好自己动手实现,考验细节处理,其它没啥好说的. #include <iostream> #include <cstdio> #include <algorithm> #include <cstring> using namespace std; ]; ]; long long GC…

简单题. 注意:读入的分数可能不是最简的.输出时也需要转换成最简. #include<cstdio> #include<cstring> #include<cmath> #include<vector> #include<map> #include<stack> #include<queue> #include<string> #include<iostream> #include<algor…

1.注意在数字和string转化过程中,需要考虑数字不是只有一位的,如300转为"300",一开始卡在里这里, 测试用例: 24/8 100/10 24/11 300/11 2.该题用到了欧几里德算法求最小公约数gcd(a,b) 算法如下: //欧几里德算法求最大公约数gcd,其中a>b long long gcd(long long a, long long b) { return b == 0 ? a : gcd(b, a%b); } AC代码如下: //#include&l…
