Instructor note:

userNum is not shown in prior code examples. This is a user defined input variable we are setting up in the code.

You don't need to know the names of the columns in this example

The solution for the code logic is all contained within the brackets of the print$()$ command.

The Cars dataset has three columns giving the quality, machining angle, and machining speed of $18$ cars.

Write a program that performs the following tasks:

Load the data Cars.csv into a data frame called cars$\_$df$.$

Subset the first userNum rows of the data frame into a new data frame.

Find and print the maximum values of each column in the subset.

Ex: If the input is:

$5$

the output is:

$\backslash$table$[[$Quality$,5],[$Speed$,4],[$Angle$,3],[$dtype:$,$int $64]]$
