Given an array of integers nums and a positive integer k, find whether it's possible to divide this array into sets of k consecutive numbers Return True if its 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 <= nums.length <= 10^5 1 <= nums[i] <= 10^9 1 <= k <= nums.length
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。
示例 1:
输入:nums = [1,2,3,3,4,4,5,6], k = 4 输出:true 解释:数组可以分成 [1,2,3,4] 和 [3,4,5,6]。 示例 2:
输入:nums = [3,2,1,2,3,4,3,4,5,9,10,11], k = 3 输出:true 解释:数组可以分成 [1,2,3] , [2,3,4] , [3,4,5] 和 [9,10,11]。 示例 3:
输入:nums = [3,3,2,2,1,1], k = 3 输出:true 示例 4:
输入:nums = [1,2,3,4], k = 3 输出:false 解释:数组不能分成几个大小为 3 的子数组。
提示:
1 <= nums.length <= 10^5 1 <= nums[i] <= 10^9 1 <= k <= nums.length
