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
You are given two 0-indexed integer arraysnums1andnums2of equal lengthnand a positive integerk. You must choose a subsequence of indices fromnums1of lengthk. For chosen indicesi0,i1, ...,ik - 1, your score is defined as: The sum of the selected elements fromnums1multiplied with the ...
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] Output:4 Explanation: The longest valid subs...

There are two simple conditions that the adjacent subsequences with the largest sum must have: (a) A maximal adjacent subsequence cannot have a starting sub-subsequence with a negative sum. Eliminating such a starting sub-subsequence and starting over must result in a larger sum for the subsequen...
