array of integers, find the maximum sum of any contiguous subarray. Example: Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4] Output: 6 (corresponding to the subarray [4, -1, 2, 1]) Write a function `max_subarray_sum` that takes in an array of integers and returns the maximum sum of any contiguous subarray. Function signature: `def max_subarray_sum(arr

Assume that constants ROWS and COLS have been defined as the number of rows and columns, respectively. Also, names is a 2-D array of strings being sent to a function like this in the main function: someFunction (names) ; Which of the following would be valid function headings for the someFunction function? Please check all that apply. Wrong answers will subtract points. O void someFunction (string names [ROWS] []) O void someFunction (string names [] [COLS]) O void someFunction (string myStrings [] [COLS]) O void someFunction (string names[] []) O void someFunction (string names [ROWS] [COLS]) O void someFunction (string names[COLS] [ROWS]) Here is an array definition: string cities [10] [25] [30] [5]: a. How many elements does the array contain? If this would cause an error, enter -999 b. For this part, assume that the definition is valid. Please write the code to assign "Austin" to the first element in the array.

Php)). Given an array of integers, write a PHP function to find the maximum element in the array. PHP Function Signature: phpCopy code function findMaxElement($arr) { // Your code here } Example: Input: [10, 4, 56, 32, 7] Output: 56 You can now implement the findMaxElement function to solve this problem. Let meanswer. r.

a. Problem 1. Create an array of 30 random numbers that range between 1 and 100. Then, write a function that will receive a number from the user and determine if that number exists in the array or not. For instance, assume the array is: [2, 93, 14, 89, 12, 3, 81, 15, 14, 89, 52, 96, 71, 82, 5, 2, 41, 23, 52, 59, 44, 44, 88, 39, 49, 50, 97, 45, 48, 36] Now, assume the user enters 89, the program should output true. But, if the user enters 77, the program should output false. Approach: We will be implementing this method in two different ways. Both will be recursive. First, implement a method called findA (x,A), where x is the number we are looking for and A is an array. In the body of the function, compare x with the FIRST item that is in the array. If this first item is equal to X, return true. If not, remove the first item from A and call findA (x,A) on the revised list. If you call find on an empty list, you will want to return false. Writing any explicit loop in your code results a…
