# Method name: min
# Input: a list of numbers

# In English, the "min" method takes as input a list of numbers and
# returns the SMALLEST number in that list.

# Your job here is to fill in the ______.  Be deliberate, don't just guess!
# The number of spaces (____) is meaningless; it's not as if four blank spots
# means you need to replace it with a 4-character chunk of Ruby.

# This is going to be very similar to max, so don't be afraid if
# these two methods look almost identical
def min(list)
  ____ = ____
  ____.each do |____|
    if ____
      ____ = ____
    end
  end
