HTML and Sinatra really only support the GET and the POST methods. In order to be able to use the PUT and DELETE methods in Sinatra, you kind of have to "trick" the form to go to the right place. Then you can name the routes the proper way - otherwise you can only really work with GET and POST.

I used the Craiglist Jr challenge for some examples. Let's look at a quick example of a POST form/method/route- in this case, we're creating a new Craigslist article:

POST form and corresponding route:

<form action="/article/new" method="post">

#Bubble Sort
# Bubble sort allows you to arrange a list in order from smallest to largest values by iterating over items in a list two at a it. Bubble sort starts at the left side of the list and compares the first two values to each other to ans swaps the values until the smaller value is on the left and the larger value is on the right. It continues to teh seond two items, comparing them; and iterates through the rest of the list in the same manner, assuming the last number is sorted. Repeat this process across the array until ifnished, ignoring sorted numbers.

def bubble(array)
  num = array.length
  loop do 
    sorted = false
    
    (num-1).times do |i|
      if array[i] > array[i + 1]
