科学计数法是科学家用来表示很大或很小的数字的一种方便的方法,其满足正则表达式 [+-][1-9].[0-9]+E[+-][0-9]+,即数字的整数部分只有 1 位,小数部分至少有 1 位,该数字及其指数部分的正负号即使对正数也必定明确给出. 现以科学计数法的格式给出实数 A,请编写程序按普通数字表示法输出 A,并保证所有有效位都被保留. 输入格式: 每个输入包含 1 个测试用例,即一个以科学计数法表示的实数 A.该数字的存储长度不超过 9999 字节,且其指数的绝对值不超过 9999. 输出格式…

题意: 给出科学计数法的形式,转化成常规的表示,要求保留所有的有效位数 思路:纯粹的字符串处理问题,注意边界条件即可.如+1.23E+02这种,转化后是123,既不需要补0,也不需要添加小数点. 代码: #include <iostream> #include <string> using namespace std; string change(string str) { string ans,sign; ]=='-') sign="-"; str.erase…

PAT 1073. 多选题常见计分法 批改多选题是比较麻烦的事情,有很多不同的计分方法.有一种最常见的计分方法是:如果考生选择了部分正确选项,并且没有选择任何错误选项,则得到50%分数:如果考生选择了任何一个错误的选项,则不能得分.本题就请你写个程序帮助老师批改多选题,并且指出哪道题的哪个选项错的人最多. 输入格式: 输入在第一行给出两个正整数N(<=1000)和M(<=100),分别是学生人数和多选题的个数.随后M行,每行顺次给出一道题的满分值(不超过5的正整数).选项个数(不少于2且不超过…
