Almost-Palindrome Sieve

Write a function that takes in an array of integers and returns the integers that are either palindromes or almost-palindromes. An almost-palindrome is any integer that can be rearranged to form a palindrome.

For example, the numbers 677 and 338 are both almost-palindromes, since they can be rearranged to form 767 and 383, respectively.

Examples

palindromeSieve([443, 12, 639, 121, 3232]) ➞ [443, 121, 3232]
// Since 443 => 434; 121 is a palindrome; 3232 => 2332 or 3223

palindromeSieve([5, 55, 6655, 8787]) ➞ [5, 55, 6655, 8787]
// Single-digit numbers are automatically palindromes.

palindromeSieve([897, 89, 23, 54, 6197, 53342]) ➞ []

Notes

Return an empty array if none of the numbers are palindromes or almost-palindromes.
