Some simple exercises completed in Ruby
my_enumerable Recreated some of the functionality of the Enumberable module in my own version.
caesar_cipher Moves letters in a string up or down the alphabet.
stock_picker Determines most profitable buy/sell option for a given stock where the price each day is given as an array of numbers.
substrings Counts the instances of strings in a dictionary that occur in a given string. Returns the result in a hash of strings => occurences.
bubble_sort Sorts an array using a simple bubble sort - comparing elements to their neighbours on the right and switching if <=> evaluates to greater than zero.
bubble_sort_by Sorts an array using a bubble sort based on a condition passed in a block. If the block condition evaluates to greater than 1, the elements are switched.
string_shuffle Takes a string and returns that string with the characters shuffled.
fibonacci Prints a fibonacci sequence to a given length. Run through ruby interpreter in console.
prime_factors Prints the prime factors of any given integer. Run through ruby interpreter in console.
happy_numbers Prints the first 8 Happy Numbers, as defined on wikipedia here. Run through ruby interpreter in console.
cost_of_tiles Asks the user for the height and width of a floor and the cost per unit square of tiles, then returns the total cost of tiling that floor. Run through ruby interpreter in console.
dungeon_crawler A basic text based dungeon crawler adventure game. To play open the file with a ruby interpreter in the terminal. Eg $ruby dungeon_crawler.rb. Nowhere near complete, no error handling yet and not very fun because there are only 3 rooms.
TicTacToe Play Tic Tac Toe on the command line with 2 players. To run simply open the file from the command line with a rubby interpreter. Eg $ruby TicTacToe.rb.
