|
||
|
|
// 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
