// EXERCISE: Slicing the Housing Prices
//
//  We have received housing prices. Your task is to print only the requested
//  columns of data (see the expected output).
//
//  1. Separate the data by the newline ("\n") -> rows
//
//  2. Separate each row of the data by the separator (",") -> columns
//
//  3. Find the from and to positions inside the columns depending
//     on the command-line arguments.
//
//  4. Print only the requested column headers and their data
//
//
// RESTRICTIONS
//
//  + You should use slicing when printing the columns.
//
//
// EXPECTED OUTPUT
