    698 - Partition to K Equal Sum Subsets.

    Medium

    Given an integer array nums and an integer k, return true if it is possible to divide this array into k non-empty subsets whose sums are all equal.

    Example 1:

    Input: nums = [4,3,2,3,5,2,1], k = 4

    Output: true

    Explanation: It is possible to divide it into 4 subsets (5), (1, 4), (2,3), (2,3) with equal sums.

    Example 2:

    Input: nums = [1,2,3,4], k = 3

    Output: false

    Constraints:

    • 1 <= k <= nums.length <= 16
    • 1 <= nums[i] <= 104
    • The frequency of each element is in the range [1, 4].
