int[] data = {2, 34, 57, 31, 5, 79, 88, 62, 98, 53, 42};
//-----------Start below here. To do: approximate lines of code = 2
// Write a loop to print out even indices (NOTE: not the elements) of array data
// use System.out.print, not System.out.println so the numbers are printed on one line
//-----------------End here. Reminder: no changes outside the todo regions.
System.out.println();
System.out.println("EXPECTED:") ;
System.out.println("0 2 4 6 8 10");
//-----------Start below here. To do: approximate lines of code = 3
// Write a loop to print out even integer elements stored in array data
// Hint: use the modulus operator % to determine if an integer element is even
//-----------------End here. Reminder: no changes outside the todo regions.
System.out.println();
System.out.println("EXPECTED:") ;
System.out.println("2 34 88 62 98 42");
//-----------Start below here. To do: approximate lines of code = 2
// Print out the elements in reverse order
//Hint: use a for loop but start at the end of the array and count down
//-----------------End here. Reminder: no changes outside the todo regions.
System.out.println();
System.out.println("EXPECTED:") ;
System.out.println("42 53 98 62 88 79 5 31 57 34 2");
