Exercise 1

Set a timer for 10 minutes.

Your challenge is to debug the program below before the timer goes off. When you fix the program or the timer goes off, move on to the next exercise.

def say_hello(name) return "hello #(name)" end

Intended output:

> say_hello("kay")

=> "hello kay"

Exercise 2

Set a timer for 10 minutes.

Your challenge is to debug the program below before the timer goes off. When you fix the program or the timer goes off, move on to the next exercise.

def encode(plaintext, key) cipher = key.chars.uniq + (('a'...'z').to_a - key.chars) ciphertext_chars = plaintext.chars.map do |char| (65 + cipher.find_index(char)).chr end return ciphertext_chars.join end

def decode(ciphertext, key) cipher = key.chars.uniq + (('a'...'z').to_a - key.chars) plaintext_chars = ciphertext.chars.map do |char| cipher[65 - char.ord] end return plaintext_chars.join end

Intended output:

> encode("theswiftfoxjumpedoverthelazydog", "secretkey")

=> "EMBAXNKEKSYOVQTBJSWBDEMBPHZGJSL"

> decode("EMBAXNKEKSYOVQTBJSWBDEMBPHZGJSL", "secretkey")

=> "theswiftfoxjumpedoverthelazydog"
