Can you solve this real interview question? Maximum Alternating Subsequence Sum - The alternating sum of a 0-indexed array is defined as the sum of the elements at even indices minus the sum of the elements at odd indices. * For example, the alternatin
Given an integer arraynums, find a contiguous non-empty subarray within the array that has the largest product, and returnthe product. It is guaranteed that the answer will fit in a 32-bit integer. A subarray is a contiguous subsequence of the array. Example 1: Input: nums = [2,3,-2...
leetcode-53-Maximum Subarray(动态规划详解) 题目描述: Given an integer arraynums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: Input: [-2,1,-3,4,-1,2,1,-5,4], Output: 6 Explanation: [4,-1,2,1] has the la...
Return the maximum score you can get by erasing exactly one subarray. An array b is called to be a subarray of a if it forms a contiguous subsequence of a, that is, if it is equal to a[l],a[l+1],...,a[r] for some (l,r). Example 1: Input: nums = [4,2,4,5,6] Out...
arr, partition the array into (contiguous) subarrays of lengthat mostk. After partitioning, each subarray has their values changed to become the maximum value of that subarray. Returnthe largest sum of the given array after partitioning. Test cases are generated so that the answer fits in a32...
Return the length of the longest valid subsequence ofnums. A subsequence is an array that can be derived from another array by deleting some or no elements without changing the order of the remaining elements. Example 1: Input:nums = [1,2,3,4] ...
