2 * [1616] Split Two Strings to Make Palindrome
3 *
4 * You are given two strings a and b of the same length. Choose an index and split both strings at the same index, splitting a into two strings: aprefix and asuffix where a = aprefix + asuffix, and splitting b into two strings: bprefix and bsuffix where b = bprefix + bsuffix. Check if aprefix + bsuffix or bprefix + asuffix forms a palindrome.
5 * When you split a string s into sprefix and ssuffix, either ssuffix or sprefix is allowed to be empty. For example, if s = "abc", then "" + "abc", "a" + "bc", "ab" + "c" , and "abc" + "" are valid splits.
6 * Return true if it is possible to form a palindrome string, otherwise return false.
7 * Notice that x + y denotes the concatenation of strings x and y.
8 *  
9 * Example 1:
10 * 
11 * Input: a = "x", b = "y"
12 * Output: true
13 * Explaination: If either a or b are palindromes the answer is true since you can split in the following way:
14 * aprefix = "", asuffix = "x"
15 * bprefix = "", bsuffix = "y"
16 * Then, aprefix + bsuffix = "" + "y" = "y", which is a palindrome.
17 * 
18 * Example 2:
19 * 
20 * Input: a = "xbdef", b = "xecab"
21 * Output: false
22 * 
23 * Example 3:
24 * 
25 * Input: a = "ulacfd", b = "jizalu"
26 * Output: true
27 * Explaination: Split them at index 3:
28 * aprefix = "ula", asuffix = "cfd"
29 * bprefix = "jiz", bsuffix = "alu"
30 * Then, aprefix + bsuffix = "ula" + "alu" = "ulaalu", which is a palindrome.
31 * 
32 *  
33 * Constraints:
34 * 
35 * 	1 <= a.length, b.length <= 10^5
36 * 	a.length == b.length
37 * 	a and b consist of lowercase English letters
38 *
