Complete the Car class by creating an attribute purchase$\_$price $($type int$)$ and the method print$\_$info$()$ that outputs the car's information. Ex: If the input is:

$[2011$; $18000$; $2018]$

where $2011$ is the car's model year, $18000$ is the purchase price, and $2018$ is the current year, then print$\_$info$()$ outputs: Car's information: Model year: $2011$ Purchase price: $ $18000$ Current value: $ $5770$
