Question

Write a program that reads an integer from the user, then creates an array of integers of that length. It then fills the array with integers read from the user. a) In your program’s main class, define a static method printArray that takes an array of integers as its only argument and prints the elements of the array. You should print all the elements of the array on one line, separated by spaces, with no extra space after the last element. b) Extend your program to print the index of the middle element of the array and the value stored in the array at that index. c) Extend (1 + (1/n)) n your program to compute the minimum value in the array and print it out. d) Extend your program to read an integer from the user and add it to every element of the array. Print the array after changing it.

Answer 1

In Python, this is straightforward using list comprehensions. List comprehensions are just a shortcut for writing a for loop on an iterable like a list. Here's an answer that solves most of the requirements for your program:

length = int(input("How long would you like the array to be?"))

arr = [input("Next?") for _ in range(length)]

print(" ".join([str(i) for i in arr]))

middle = len(arr) // 2

print(arr[middle])

print(min(arr))

to_add = int(input("Input a number to add to all elements"))

arr = [to_add + i for i in arr]

print(" ".join([str(i) for i in arr]))
