--> node problemOne.js '[{"PKG":"2", "weight":75,"distance": 125,"offering":"off002"}, ...more]'
--> node problemTwo.js 'no_vehicle' 'max_speed' 'max_weight' '[{"PKG":"2", "weight":75,"distance": 125,"offering":"off002"}, ...more]'
-> Group.js --> This will return an array according to condition that states 'No PKG weight should be greater than N & max package should deliver at once'
-> module.js --> This will return Discounted value of packages and takes user input.
-> Offers --> Offers are present in module.js , we change the variable value there only or we can create JSON file seperate
Usage - Mainly we need to test grouping & Discount function (You can add more custom test cases there )
--> node group.test.js
--> node module.test.js
