The Playlist Shuffle Check

Your friend swears they only SHUFFLED your playlist. Same songs, same repeats, new order — verify the claim. 🎧

You get the before list and the after list. Print true shuffle if they hold exactly the same songs the same number of times, otherwise songs changed.

Example:

Input: before = ["hey", "sun", "hey", "rain"], after = ["rain", "hey", "sun", "hey"] Output: true shuffle

Both lists hold the exact same songs the same number of times (hey×2, sun×1, rain×1) — just reordered.
