in C programing Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b,4) should return 0.int isSorted(int *array, int n){
Write code in assembly language Question 1: Construct a program using 2D array. Define a list of strings in the 2D arrays, the list should be only a string. Get a string from a user as input Search the user's string in the list of strings. If string is found print the string, and a message "String is Found". If string is not found print only a message "String is Not Found".
Write a function definition named first_and_second that takes in sequence and returns the first and second value of that sequence as a list. This is in python Also assert, assert first_and_second([1, 2, 3, 4]) == [1, 2] assert first_and_second(["python", "is", "awesome"]) == ["python", "is"] assert first_and_second(["strawberry", "kiwi", "mango", "guava"]) == ["strawberry", "kiwi"]

Using c++ Contact list: Binary Search A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Frank 867-5309 Joe…
