Combine Two Lists

Given two provided Lists of Integer called firstList and secondList$,$ combine the elements of both Lists into one new List.

$-$ Instantiate a new List, combinedList.

$-\backslash (\backslash$quad $\backslash )$ Put each element from firstList into combinedList.

$-$ Put each element from secondList into combinedList.

$-$ Finally, print the elements of combinedList to the console.
