Compute Encoded Product Name

Amazon's software team utilizes several algorithms to maintain data integrity, one of which targets the encoding of symmetrical names. Symmetrical names are unique in that they read identically in both directions, similar to palindromes in language parlance.

The chief aim of the algorithm is to rearrange the characters in the original symmetrical name according to these criteria:

The rearranged name is a reshuffled version of the original symmetrical name.

The restructured name should be symmetrical as well.

This restructured name should be lexicographically smallest among all its symmetric permutations.

Given an initial symmetrical name that contains only lowercase English characters, compute the encoded name.

A string is considered to be lexicographically smaller than the string t of the same length if the first character in s that differs from that in t is smaller. For example, "abcd" is lexicographically smaller than "abdc" but larger than "abaa".

Note that the output encoded name could match the original name if it's already the smallest lexicographically.
