题目要求 Given an array A of integers, return true if and only if we can partition the array into three non-empty parts with equal sums. Formally, we can partition the array if we can find indexes i+1 < j with (A[0] + A[1] + ... + A[i] == A[i+1] + A[i+2]…

简单题,暴力找出来就行. class Solution: def canThreePartsEqualSum(self, A: List[int]) -> bool: s = sum(A) if s % 3 > 0: return False s /= 3 size = len(A) t = 0 a, b = -1, -1 for i in range(size): t += A[i] if t == s: a = i break t = 0 for j in range(size - 1,…

Given an array of integers nums and a positive integer k, find whether it's 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's possible…

Given a non-empty array containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal. Note: Both the array size and each of the array element will not exceed 100. Exam…
