做了Zenefits的OA,比面经里的简单多了..害我担心好久 阴险的Baidu啊,完全没想到用二分,一开始感觉要用DP,类似于极小极大值的做法. 然后看了答案也写了他妈好久. 思路是再不看M的情况下,最终结果的取值范围是[最大的元素,所有元素之和],然后就是用二分在这个范围里找. 注意二分的取舍要配合取舍方程,我用的方程是,保证子集的和都小于等于二分测试的那个二分M,然后集合数小于要求的m.一旦子集数量超过m,说明我们测试的二分M太小了,弄大点,才能让每个子集多放点元素,从而使得总子集数不超过…
思路: dp. 实现: class Solution { public: int splitArray(vector<int>& nums, int m) { int n = nums.size(); vector<, ); ; i <= n; i++) sum[i] = sum[i - ] + nums[i - ]; vector<vector<, vector<, INT_MAX)); ; i <= n; i++) dp[i][] = sum[i…
给定一个非负整数数组和一个整数 m,你需要将这个数组分成 m 个非空的连续子数组.设计一个算法使得这 m 个子数组各自和的最大值最小.注意:数组长度 n 满足以下条件:    1 ≤ n ≤ 1000    1 ≤ m ≤ min(50, n)示例:输入:nums = [7,2,5,10,8]m = 2输出:18解释:一共有四种方法将nums分割为2个子数组.其中最好的方式是将其分为[7,2,5] 和 [10,8],因为此时这两个子数组各自的和的最大值为18,在所有情况中最小.详见:https:…

2019-10-14 22:13:18 问题描述: 问题求解: 解法一:动态规划 这种数组划分的题目基本都可以使用dp来解决,核心的思路就是先维护低的划分,再在中间找分割点加入新的划分. public int splitArray(int[] nums, int m) { int n = nums.length; long[][] dp = new long[m + 1][n]; long[] presum = new long[n]; presum[0] = nums[0]; for (int…
Given an array with n integers, you need to find if there are triplets (i, j, k) which satisfies following conditions: 0 < i, i + 1 < j, j + 1 < k < n - 1 Sum of subarrays (0, i - 1), (i + 1, j - 1), (j + 1, k - 1) and (k + 1, n - 1) should be…

概述 Array是JavaScript的内置对象,同时也是一个构造函数,可以用它生成新的数组. 作为构造函数时,Array可以接受参数,但是不同的参数,会使得Array产生不同的行为. 无参数时,返回一个空数组: 如果使用一个正整数作为参数,则这个正整数表示新数组的长度: 如果使用非数值(字符串.布尔值.对象等)作为参数,则该值是新数组的成员: 如果参数在一个以上,则这些参数都是新数组的成员. var a1 = new Array(); var a2 = new Array(1); var a3…
17.12 Design an algorithm to find all pairs of integers within an array which sum to a specified value. 这道题实际上跟LeetCode上的Two Sum很类似,但是不同的是,那道题限定了只有一组解,而这道题说可以有很多组符合要求的解,那么我们先来看一种使用哈希表的解法,这种解法的时间复杂度是O(n),空间复杂度是O(1),思路是用哈希表建立每个数字和其下标之间的映射,遍历整个数字,如果targ…
