LCCI

There are three types of edits that can be performed on strings: insert a character, remove a character, or replace a character. Given two strings, write a function to check if they are one edit (or zero edits) away.

&nbsp;

Example&nbsp;1:

<pre>
Input: 
first = &quot;pale&quot;
second = &quot;ple&quot;
Output: True
</pre>

Example&nbsp;2:

<pre>
Input: 
first = &quot;pales&quot;
second = &quot;pal&quot;
Output: False
</pre>

String

字符串有三种编辑操作:插入一个英文字符、删除一个英文字符或者替换一个英文字符。 给定两个字符串，编写一个函数判定它们是否只需要一次(或者零次)编辑。

输入：
first = "pale"
second = "ple"
