##### Question
LeetCode 266. Palindrome Permutation – Given a string, determine whether any permutation can form a palindrome. Follow-up: If a palindrome permutation exists, generate and return one such palindrome. Implement addition of two non-negative decimal numbers represented as strings (the numbers may contain a decimal point) without using built-in arbitrary-precision types.
