dmin = min( digits )            # min( x ): # gives you back the minimum value within x
# lexicographical order: ordering by the value of each character in the alphabet
# a is the minimum value and z is the max value
# when max() and min() compares between strings, they compare EACH CHARACTER AT A TIME
# 'we' vs 'are'
#   compares 'w' vs 'a' --> 'w' > 'a' in the lexicographical order
# 'in' vs 'it'
#   compares 'i' vs 'i' --> they're equal --> move on
#   compares 'n' vs 't' --> 'n' < 't' --> so 'in' comes before 'it'
