题目1描述

编程实现在字符串的指定位置进行插入新一字符串，然后再将结果反序输出。例如，现有字符串aaaaa，然后要求在该字符串的第2个字符（从左到右数）的后面，插入新的字符串bbb，则反序输出的结果是aaabbbaa（注意，所有的字符串长度，无论是原本字符串的长度、待添加的字符串长度还是插入后总的字符串长度，都不超过100，而且这些字符串只含有数字字母字符）。-Topic 1 describes the programming insert a new string specified position in the string, and then the results in reverse order output. For example, the existing string aaaaa, then request later in the first two characters of the string (from left to right number), insert a new string bbb, the results of the anti-sequence output aaabbbaa (all characters string length, whether it is the original length of the string, the length of the string to be added or inserted after the total length of the string, not more than 100, and these string contains only alphanumeric characters).
