# 1. Create a `day_3` directory under the course directory.

# 2. Save this file under the new folder as `warmup.rb`.

# 3. Assign any string value to a variable.

# 4. Assign any whole number to a variable.

# 5. Assign any decimal number to a variable. 

# 6. Add each of the previous variables to a collection.

# 7. Output the number of items in the collection.

# 8. Iterate through the collection and output each item.

# 9. Create a dictionary with your name, birth month, and birth day.

# 10. Using the dictionary from the previous step, output the following message:
#       My name is _ and my birthday is on _.

# 11. Add the dictionary from step 10 to the collection of items from step 6.

# 12. Create a function which returns an "ordinal indicator" for a number.
# 
#     In written languages, an ordinal indicator is a character, or group of 
#     characters, following a numeral denoting that it is an ordinal number, 
#     rather than a cardinal number.
#     In English orthography, this corresponds to the suffixes -st, -nd, -rd,
#     -th in written ordinals represented as 1st, 2nd, 3rd, 4th, etc.
