https://leetcode.com/problems/divide-array-in-sets-of-k-consecutive-numbers

Description

Given an array of integers nums and a positive integer k, find 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:** true
**Explanation:** Array can be divided into [1,2,3] , [2,3,4] , [3,4,5] and [9,10,11].

Example 3:

**Input:** nums = [3,3,2,2,1,1], k = 3
**Output:** true

Example 4:

**Input:** nums = [1,2,3,4], k = 3
**Output:** false
**Explanation:** Each array should be divided in subarrays of size 3.

Constraints:

• 1 <= k <= nums.length <= 105

• 1 <= nums[i] <= 109
