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: Each of the array element will not exceed 100.The array size will not exceed 200. Example 1: Input: [1, 5, ...
Elements in the given array will be in range [-1,000,000, 1,000,000]. 这道题给了我们一个数组,让我们找出三个位置,使得数组被分为四段,使得每段之和相等,问存不存在这样的三个位置,注意三个位置上的数字不属于任何一段。刚开始博主觉得这题貌似跟之前那道Partition Equal Subset Sum很像,所以在想...
Given an array S of n integers, are there elements a, b, c in S such that a + b + c = 0? Find all unique triplets in the array which gives the sum of zero. Note: Elements in a triplet (a,b,c) must be in non-descending order. (ie, a ≤ b ≤ c) The solution set mus...
The triangular sum ofnumsis the value of the only element present innumsafter the following process terminates: Letnumscomprise ofnelements. Ifn == 1, end the process. Otherwise, create a new 0-indexed integer arraynewNumsof lengthn - 1. ...
Given an integer array nums and two integers firstLen and secondLen, return the maximum sum of elements in two non-overlapping subarrays with lengths firstLen and secondLen. The array with length firstLen could occur before or after the array with length secondLen, but they have to be non...
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: Each of the array element will not exceed 100. The array size will not exceed 200. ...
LeetCode: 327. Count of Range Sum LeetCode: 327. Count of Range Sum Given an integer array nums, return the number of range sums that lie in [lower, upper] inclusive. Range sum S(i, j) is defined as the sum of the elements in nums between indices i and j (i ≤ j), inclusive...
