Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Return the centered average of an array, which is the mean average of the values, ignoring the largest
and smallest. If there are multiple copies of the smallest or largest values, ignore just one. If the array
length is less than 3, then return 0.

Create a program that will encrypt letters and create a secret code. You will create an array of numbers from 0 - 25. use [i for i in range (26)] to create an array of numbers from 0 - 25. use random.shuffle to to shuffle the above array. This will be used for a new letter index order. For example: The first created array [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25] gets shuffled to become[2, 14, 12, 20, 16, 5, 11, 1, 13, 17, 15, 21, 19, 10, 23, 22, 25, 3, 6, 7, 18, 4, 9, 24, 0, 8] This will be used as the new index for the encrypted alphabet. create an array of letters using list(string.ascii_lowercase), this requires importing the string module.

1. In javascript. Declare an array to hold eight integers. Use a for loop to add eight random integers, all in the range from 50 to 100, inclusive, to this array. Duplicates are okay. Next, pass the array to a method that sorts the array and returns another array containing only the largest and smallest elements in the original array. Print these two values in main. Then use a foreach loop to display all elements of the sorted array on one line separated by a single space. This latter loop should also count the odd and even numbers in the array and determine the sum of all elements in the array.
