TILbot

TILbot helps you reinforce what you learn. Get started by giving TILbot a question and answer, just like you were creating a flashcard. TILbot calls these TILcards. Congrats, this is your first act of learning reinforcement!

Your First TILcard

Let's say this is your first TILcard:

# Given a file containing order line items in the form [User ID]: [Medications] where medications are separated by commas, determine the pairs of medications that appear most frequently together.

# For example:

# Given two line items

# Zestril, atorvastatin, Levoxine
# Zestril, atorvastatin, Orasone

# The function should output the pair Zestril, atorvastatin.

# Create a calculator that takes integers separated by the basic mathematical operators (+,-,*,/) and returns the result.

# You can use Ruby's mathamatical methods(+, -, *, /).
# The priority is on working code, not brevity.

# 7 + 2 - 3 / 4 * 5 = 5.25

#math_characters = '7 + 2 - 3 / 4 * 5'
