leetcode548 Split Array with Equal Sum】的更多相关文章

思路: 使用哈希表降低复杂度.具体来说: 枚举j: 枚举i,如果sum[i - 1] == sum[j - 1] - sum[i],就用哈希表把sum[i - 1]记录下来: 枚举k,如果sum[k - 1] - sum[j] == sum[n - 1] - sum[k]并且哈希表中存在sum[k - 1] - sum[j],返回true. 返回false. 实现: class Solution { public: bool splitArray(vector<int>& nums)…

Given a string S of digits, such as S = "123456579", we can split it into a Fibonacci-like sequence [123, 456, 579]. Formally, a Fibonacci-like sequence is a list F of non-negative integers such that: 0 <= F[i] <= 2^31 - 1, (that is, each…
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…
