Split Two Strings to Make Palindrome

Description

You are given two equal-length strings a and b. Split both at the same index to get aprefix + asuffix and bprefix + bsuffix. Either prefix or suffix may be empty. Return true if aprefix + bsuffix or bprefix + asuffix forms a palindrome for some split index.

Example 1:

Input: a = "x", b = "y"

Output: true

Explaination: If either a or b are palindromes the answer is true since you can split in the following way:

aprefix = "", asuffix = "x"

bprefix = "", bsuffix = "y"

Then, aprefix + bsuffix = "" + "y" = "y", which is a palindrome.

Example 2:

Input: a = "xbdef", b = "xecab"

Output: false

Example 3:

Input: a = "ulacfd", b = "jizalu"

Output: true

Explaination: Split them at index 3:

aprefix = "ula", asuffix = "cfd"

bprefix = "jiz", bsuffix = "alu"

Then, aprefix + bsuffix = "ula" + "alu" = "ulaalu", which is a palindrome.
