Part 3 Coding Exercise: Decoding a Message from a Text File In this exercise, you will develop a function named "decode(message file)". This function should read an encoded message from a .txt file and return its decoded version as a string. Note that you can write your code using any language and IDE you want (Python is preferred if possible, but not mandatory). Your function must be able to process an input file with the following format: $0.00 3 love 6 computers 2 dogs 4 cats 11 5 you In this file each line contains a number followed by a word. The task is to decode a hidden message based on the arrangement of these numbers into a "pyramid" structure. The pyramid increases by one number per line, like so: 1 23 456 The key to decoding the message is to use the words corresponding to the numbers at the end of each pyramid line (in this example, 1, 3, and 6). You should ignore all the other words. So for the example input file above, the message words are: 1: I 3: love 6: computers and your function should return the string "I love computers". Please submit the complete code for the decode function along with a brief explanation of how your code works: Your explanation should be written as a few sentences at minimum, please don't rely just on comments
