A - Divisible Problem Statement You are given positive integers N N N and K K K, and a sequence of length N N N, A = ( A 1 , A 2 , … , A N ) A=(A_1,A_2,\ldots,A_N) A=(A1,A2,…,AN). Extract all
Given a non-empty array of integers, return the k most frequent elements. For example, Given [1,1,1,2,2,3] and k = 2, return [1,2]. Note: You may assume k is always valid, 1 ≤ k ≤ number of uni
