 You have an array of integers, and for each index you want to find the product of every integer except the integer at that index.

Write a function get_products_of_all_ints_except_at_index() that takes an array of integers and returns an array of the products.

For example, given:

  [1, 7, 3, 4]

your function would return:

Codebreakers

We're going to be writing a program to do some basic text encryption through everyone's friend, the command line.

Iteration 1 - Initials

We're first going to start with an exercise to figure out how we can get code entered on the command line.

Create a file called initials.rb.

Exercises

• If you had an array of numbers, e.g. [1,2,3,4], how do you print out the doubles of each number? Triples?
• If you had the same array, how would you only print out the even numbers? What about the odd numbers?
• How could you create a new array which contains each number multipled by 2?
• Given an array of first and last names, e.g. ["Alice Smith", "Bob Evans", "Roy Rogers"], how would you print out the full names line by line?
• How would you print out only the first name?
