Example 4:
Input: s = "a"
t = "a"
Output: false
Explanation:
Given two strings s and t, return true if they are both exactly one edit distance apart, otherwise return false.
A string s is said to be one edit distance apart from a string t if you can transform s into t by performing exactly one of the following operations:
s to get t.s to get t.s with a different character to get t.Equal strings are not one edit distance apart — the count of edits must be exactly one.
Insert c into s between a and b to get t.
These strings differ by more than one edit.
Replace 0 in s with 1 to get t.
Equal strings are zero edits apart, not one.
0 <= s.length, t.length <= 10^4s and t consist of lowercase letters, uppercase letters, and digits.
