1.5 One Away:
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
pales, pale
pale, bale
pale, bake
pale, ple
true
true
true
false

book shows:
pales, pale => true
pale, bale => true
pale, bake => false
pale, ple => true
