/**

 * @returns An array of numbers found in the string.

/**
 * * Computes the Levenshtein distance between two strings (space optimized).
 * @param str1 - First string to compare.
 * @param str2 - Second string to compare.
 * @returns The Levenshtein distance between the two strings.
 *
 * @remarks
 * - The Levenshtein distance is the minimum number of single-character edits (insertions, deletions, or substitutions) required to change one string into the other.
 * - This implementation uses only O(min(len(a), len(b))) space by keeping only the current and previous rows of the distance matrix.
 *
 * @example
 * const distance = getLevenshteinDistance('kitten', 'sitting');
 * console.log(distance); // Output: 3
