CodingDistributed systemsAlgorithms & data structuresSenior–Staff~30 min

Given an integer list nums and an integer k, return True if nums can be partitioned into exactly k non-empty subsets all having equal sum. 1 <= k <= len(nums) <= 12, values are positive. Return a boolean.

can_partition_k_subsets(nums: list[int], k: int) → bool

What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
