• We made changes on how the program read its input (through arguments instead through prompt)
• We made changes and made everything class design

Here is the problem you need to solve. You are given N number of cities. You need to design a communication network connecting these cities. The costs of connecting the cities using fiber optic cables are given. This is called a cost matrix M. M is symmetric. The reliabilities of connecting the cities (i.e., the reliabilities of the fiber optic connections between the cities) are given by the matrix R. Your program needs to output a design to meet the following requirements

• Meet a given reliability goal.
• Maximize reliability subject to a given cost constraint

Your program should take a text file as input defining the parameters. Here is the format of the input file. N # number of cities N(N-1)/2 numbers # costs of inter-city connecting N(N-1)/2 numbers # reliabilities of inter-city connections
