/**
 * Pairwise distance between two sets of observations.
 *
 * Computes various distance metrics between two arrays including
 * Euclidean, Manhattan, Chebyshev, and Hamming distances.
 *
 * @param x First input array
 * @param y Second input array
 * @param mode Distance method ('euclidean', 'manhattan', 'chebychev', 'hamming'). Default is 'euclidean'
 * @returns Distance value
 * @throws When arrays have different lengths or invalid method specified
 *
 * @example Euclidean distance
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(pdist([0, 0], [3, 4], 'euclidean'), 5);
 *
 * ```
 *
 * @example Manhattan distance
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(pdist([1, 1], [4, 5], 'manhattan'), 7);
 *
 * ```
 *
 * @example Chebyshev distance
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(pdist([1, 2], [4, 6], 'chebychev'), 4);
 * ```
