+# Write a function called remove_duplicates
+# The sole parameter of the function should be a list
+# The function should look through a list,
+# Find all duplicate elements, and remove them
+# Sort the resulting list
+# YOU MAY NOT USE THE set() function IN PYTHON.
+# Hint: To sort a list, use sorted(list)
+# Another hint: Use dict.removekeys(list)
+# To take the elements from a list,
+# and convert them to keys in a dictionary
+
+# Example: array = [1,1,2,5,4,6,12,3,4,6]
+# Result should print [1,2,3,4,5,6,12]
