Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a permutation p=[p_1, p_2, …, p_n] of integers from 1 to n. Let's call the number m (1 ≤ m ≤ n) beautiful, if there exists two indices l, r (1 ≤ l ≤ r ≤ n), such that the numbers [p_l, p_{l+1}, …, p_r] is a permutation of numbe... | instruction | 0 | 4,293 | 12 | 8,586 |
