Modify the function below to match the following description:
#
# This function takes in a dictionary dct. You can assume that the keys and
# values of the dictionary are limited to strings and numbers.
#
# If any key or value contains either MAX_DIGIT or the first letter of your
# last name (in either upper or lower case) then the key-value pair is removed
# and the modified dictionary is returned. Here containment means that the
# symbol is present anywhere -- e. g. 'doodle' contains letter 'd' and
# 195 contains 5
#
# Here are some examples assuming the first letter of my last name is d and
# MAX_DIGIT=5:
#
# fix_dictionary({'a':1, 3:'x', 'x':'y'})
# will return {'a':1, 3:'x', 'x':'y'} (no change)
#
# fix_dictionary({'d':1, 3:'x', 'x':'y'})
# will return {3:'x', 'x':'y'} (first key-value pair is removed)
#
# fix_dictionary({'DX':1, 3:'x', 'x':'y'})
# will return {3:'x', 'x':'y'} (first key-value pair is removed)
#
# fix_dictionary({'h':15, 3:'x', 'x':'y'})
# will return {3:'x', 'x':'y'} (first key-value pair is removed)
#
# fix_dictionary({'h':95, 3:'d', 'z':'paddle'})
# will return {} (all key-value pairs have been removed)
