# # Challenge 2 - Update Users
# 
# We at CashBox would like you to update the user with email address kimberly@yahoo.com to have the last name "Deal".
# 
# There is a misspelling of a user whose username is **jeffrey**. It should only be one `f`, **jefrey**.
# 
# There are a couple ways to make this change happen, let's see what you can figure out!
# 
# After you've completed the TODO's click the `Run Tests` button
