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.

Example 1:

Input: 

first = "pale"

second = "ple"

Output: True

Example 2:

Input: 

first = "pales"

second = "pal"

Output: False
