I solvedthisproblem using technique which is mentioned ineditorial. Then I came up with a different approach: we can iterate through the possible length of a subarray, pick one with the largest sum, update the answer. However, I don't know how to implement finding a subarray with length =...
reducing subarry product problem to subarray sum problem. For each index i, find the rightmost index j such that prefix[j] - nums[i-1] < Math.log(k). Note the comparison for double, reduce log(k) by 1e-9, to avoid searching the wrong half. ...
Can you solve this real interview question? Continuous Subarray Sum - Given an integer array nums and an integer k, return true if nums has a good subarray or false otherwise. A good subarray is a subarray where: * its length is at least two, and * t
Given an array of n positive integers and a positive integer s, find the minimal length of a contiguous subarray of which the sum ≥ s. If there isn’t one, return 0 instead. Example: Input: s = 7, nums = [2,3,1,2,4,3] ...
