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.

Need help with this debuggin exercise. 1.) Assume the following main module is in a program that includes the binarySearch function. Why doesn't the pseudocode in the main module work? //This program uses the binarySearch function to search for a //name in the array. This program assumes the binarySearch //function has alreday been defined. Modulemain() Constant Integer SIZE= 5 Declare String names[SIZE]= "Zack", "James", "Pam", "Marc", "Susan" Declare String searchName Declare Integer index Display "Enter a name to search for." Input searchName Set index = binarySearch(names, searchName, SIZE) If index != - 1 Then Display searchName, " was found." Else Display searchName, " was NOT found." End IF End Module All coding is in Python.
Using C Program and arrays, Write a program that will give the sum of the main and opposite diagonal elements of a square matrix.

Language: C Print a Mayo pyramid with # characters depending on user input, i.e., the pyramid height h. To this end, update the size of the array for each level of the pyramid (for each for loop passing) using the realloc function. First of all, allocate an array for the first row. You need the allocate the memory for h + 2 characters for the first row. Fill it with spaces, using the memset(row, ’ ’, h+2) command. For each row i, expand the array size to h + 4 + i, replace the last two characters of the line with # sign, followed by the string’s null terminator. That’s why you need increase the size by 2, with the respect to the original allocation, and then by 1 at each step. You also need to replace the space at the position h − 1 − i with the # character (the left slope of the pyramid). Print and examine your results, free the memory and use the valgrind function to check memory usage.
