# You may modify the lines of code above, but don't move them!

# In math, factorial is a mathematical operation where an
# integer is multipled by every number between itself and 1.
# For example, 5 factorial is 5 * 4 * 3 * 2 * 1, or 120.
# Factorial is represented by an exclamation point: 5!
#
# Use a for loop to calculate the factorial of the number
# given by mystery_int above. Then, print the result.
#
# Hint: Running a loop from 1 to mystery_int will give you
# all the integers you need to multiply together. You'll need
# to track the total product using a variable declared before
# starting the loop, though!

# 4 d

# Note that the first item is #0, the second is #1, and so
# on! We'll talk about why that is in Unit 4.

# Hint: You'll need a separate variable to keep track of how
# many letters you've printed! You may not use the range
# function on this problem.
