写这道题时都使用了现成的函数，stoi(),to_string()等,但是这样一直有两个测试点显示运行时错误。最后排查出发现是stoi这个函数（to_string没测估计也有问题)，基本上是因为题目中说过最大数据为1000位，所以这个函数就出错了。只适用于较小的数据吧。代码：#include<iostream>#include<stdio.h>#include&lt...

提交以后错了最后两个测试点：更改后发现最后两组数据的id小于7位数，或者有前导0，所以输出的时候要按照“%07d"格式。也接着上一题学到的stringstream成功分割了keyword中的字符串，简洁了很多在这里插入代码片#include<iostream>#include<stdio.h>#include<stdlib.h>#include&lt...

PAT 1071错误点：没有处理最后一个单词。在对整行字符串处理时，如果最后一个单词为有效字符，那么就没有对他放入map操作而是直接结束放入map的所有过程开始遍历找最大了。所以需要在while结束后对最后一个单词进行补充处理。#include<iostream>#include<stdio.h>#include<stdlib.h>#include&l...

主要讲错误点：算法笔记给出的一组用例：43 4 2 13 4 2 1//ouputInsertion Sort2 3 4 1可以用来检查自己的匹配插入排序的函数是否正确。有没有正确的处理初始序列和中间序列一致的情况。代码如下：#include<iostream>#include<stdio.h>#include<stdlib.h>#i...
