GitHub PDF 1001. A+B Format (20) Calculate a + b and output the sum in standard format -- that is, the digits must be separated into groups of three by commas (unless there are less than four digits). 解题思路 将a+b的值先存在sum中,再逐个分解sum的数字,将组成sum的所有数字存到数组中,由…

题目链接:传送门 题目简述: 1. 给定两个整数值a,b: 2.范围-1000000 <= a, b <= 1000000: 3.按指定格式输出结果 例:-100000 9 输出: -99,991 解题思路: 1.明确范围     a+b在正负两百万范围内, 32位系统int类型占4字节精度够 2.明确要求: ① 输入以空格分割, 输入整数 ②结果如果数字大于4位, 需要每三位用逗号分割 ③视算法可能有需要补零的情况(我就是踩的这个坑) ④正负号提前判定, 便于后面处理 ⑤函数要以return…

题目: 我一开始的思路是: 用math.h中的log10函数来计算位数(不建议这么做,因为会很慢,而且会出一点别的问题): 用pow函数根据要插入分号的位置来拆分a+b成一个个数字(例如res / pow(10, len - 3)来获得千位以前的数字),从左往右依次输出,同时在对应位置输出,: 也就是说,我这里的思路是直接用数字来进行处理的,但是这样做其实非常低效而且很容易写错代码,因此我看了下柳婼的代码,换成了这个思路:先将计算结果转换为字符串后进行处理.这样就会简单许多: #include…
