Question
You are to write a Trip Distance Calculator that calculates the approximate driving distance for a trip the visits multiple cities.
The approximate driving distance between two cities is often depicted in a mileage chart. I mileage chart is a two-dimensional table that lists across rows and columns. To find the distance between two cities, find the cell that is the intersection between the origination city row and the destination city column (or vice versa). A sample mileage chart is listed below.

Table 1 Mileage Chart Distance Between Some USA Cities
Requirements
Write a program that lists a menu of cities, including an exit option, and keeps track of the total estimated driving miles as each city is chosen. When the user exits, the final total estimated driving miles are displayed.
You must use the mileage data list in Table1. You are allowed to augment the list. For example, you can add Indianapolis, but you must leave the existing cities. Adding a city requires you to include all the estimated driving distances to all the current cities.
Driving from a city to itself gives a distance of 0. This corresponds to the diagonal in Table 1. All the empty cells of the table on the diagonal should be populated with 0.
The following is a sample run of your program.
