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.
true if it is possible. Otherwise, return
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].
Input: nums = [3,2,1,2,3,4,3,4,5,9,10,11], k = 3 Output: true Explanation: Array can be divided into [1,2,3] , [2,3,4] , [3,4,5] and [9,10,11].
Input: nums = [1,2,3,4], k = 3 Output: false Explanation: Each array should be divided in subarrays of size 3.
1 <= k <= nums.length <= 105
1 <= nums[i] <= 109
