ALGORITHM Quicksort(A[l..r])//Sorts a subarray by quicksort//Input: Subarray of array A[0..n − 1], defined by its left and right// indices l and r//Output: Subarray A[l..r] sorted in nondecreasing order if l < r s = Partition(A[l..r]) //s is a split position Quicksort(A[l..s − 1]) Quicksort(A[s + 1..r]) The above code is the quicksort algorithm.Perform a time complexity analysis for quicksort. You need to explain 1) what makes a worst case, what makes a best case, 2) the time complexity for both the worst case and the best case, 3) how to avoid the worst case in practice.
9.). integer array nums and an integer k, return the length of the shortest non-empty subarray of nums with a sum of at least k. If there is no such subarray, return -1. A subarray is a contiguous part of an array. Example 1: Input: nums = [1], k = 1 Output: 1 Example 2: Input: nums = [1,2], k = 4 Output: -1 Example 3: Input: nums = [2,-1,2], k = 3 Output: 3.

:::::::-::::::::: Question. Here Maximum Subarray Sum" You are given an array of integers, and your task is to find the contiguous subarray with the largest sum. The subarray must contain at least one element. Example: Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4] Output: 6 Explanation: The contiguous subarray [4, -1, 2, 1] has the largest sum, which is 6. Your task is to write a function that takes an array of integers as input and returns the maximum sum of a contiguous subarray. Constraints: The array may contain both positive and negative integers...
