+# [1296. Divide Array in Sets of K Consecutive Numbers](https://leetcode.com/problems/divide-array-in-sets-of-k-consecutive-numbers/)
+
+## 题目
+
+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: true
+ Explanation: Array can be divided into [1,2,3] , [2,3,4] , [3,4,5] and [9,10,11].
+
+**Example 3**:
+
+ 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 <= 100000
+- 1 <= nums[i] <= 1000000000
+
+## 题目大意
+
+给你一个整数数组 nums 和一个正整数 k，请你判断是否可以把这个数组划分成一些由 k 个连续数字组成的集合。
+如果可以，请返回 true；否则，返回 false。
+
+## 解题思路
+
+贪心算法
+
+- 对nums升序排序
+- 对nums内数字进行哈希计数（key:数字，value:数量）
+- 遍历nums中的数字，以数量大于1的数字作为连续数字开头，寻找连续数字后续元素，若无法找到 k 个连续数字则返回false
+- 所有数字都能找到 k 个连续数字返回true
+
+##代码
+
+```go
+package leetcode
+
+import "sort"
+
+func isPossibleDivide(nums []int, k int) bool {
+ mp := make(map[int]int)
+ for _, v := range nums {
+ mp[v] += 1
+ }
+ sort.Ints(nums)
+ for _, num := range nums {
+ if mp[num] == 0 {
+ continue
+ }
+ for diff := 0; diff < k; diff++ {
+ if mp[num+diff] == 0 {
+ return false
+ }
+ mp[num+diff] -= 1
+ }
+ }
+ return true
+}
+```
