1296. Divide Array in Sets of K Consecutive Numbers

Given an array of integers nums and a positive integer k, check whether it is possible to divide this array into sets of k consecutive numbers. Return true if it is possible. Otherwise, return false. Example 1: Input: nums = [1,2,3,3,4,4,5,6], k = 4 Output: true Explanation: Array can be divided into [1,2,3,4] and [3,4,5,6]. Example 2: Input: nums = [3,2,1,2,3,4,3,4,5,9,10,11], k = 3 Output
