/*Assumptions:
* This system is based on the following assumptions.
* 1. The numbers in the input file are all valid. Program doesnt check for validity
* Validity means - if a number is of a valid base(base < the base of the system),
* then it is expressed using symbols of that base only.
*
* 2.If any number is having a base greater than the base of the system, the system just shuts down.
* 3.If any number is expressed using symbols which the system doesnt understand, the system just shuts down.
* 4.If any of the file is not found in the given path, the system shuts down.
* 5.This uses in-place partition method.
* 6.The QuickSelect method has been exposed in two different ways. One is as per the problem statment and another is
* just as QuickSelect(int k) as the instance of the numbersystem would have all other information like numbers[], size *
