Given the array nums consisting of n positive integers. You computed the sum of all non-empty continous subarrays from the array and then sort them in non-decreasing order, creating a new array of n * (n + 1) / 2 numbers. Return the sum of the numbers from index left to index righ...
Can you solve this real interview question? Maximum Sum of Two Non-Overlapping Subarrays - 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
Can you solve this real interview question? Binary Subarrays With Sum - Given a binary array nums and an integer goal, return the number of non-empty subarrays with a sum goal. A subarray is a contiguous part of the array. Example 1: Input: nums =

so, now find no of subarrays with odd 1s for each of the bits. so how can we do this? see we can count no of subarrays starting with 0th index and have odd 1s then we can iterate over alliiletting it to be the starting index of the subarrays. ...

【leetcode】907. Sum of Subarray Minimums 题目如下: 解题思路:我的想法对于数组中任意一个元素,找出其左右两边最近的小于自己的元素。例如[1,3,2,4,5,1],元素2左边比自己小的元素是1,那么大于自己的区间就是[3],右边的区间就是[4,5]。那么对于元素2来说,和左边区间合并组成[2,3]以及和右边区间合并...
