# 12.2 (The Location class) Design a class named Location for locating a maximal
# value and its location in a two-dimensional list. The class contains the public data
# fields row, column, and maxValue that store the maximal value and its indexes in
# a two-dimensional list, with row and column as int types and maxValue as a
# float type.
# Write the following method that returns the location of the largest element in a
# two-dimensional list.
# def Location locateLargest(a):
# The return value is an instance of Location. Write a test program that prompts
# the user to enter a two-dimensional list and displays the location of the largest element
# in the list.
