This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Use the provided Java int[] backing array of length 6 and the separate logical size variable to reproduce the four logical states: [4, 2, 7], [4, 2, 7, 1], [4, 5, 7, 1], and [4, 5, 7]. Print only the logical elements, not unused backing-array positions.

[4, 5, 7, 1]
[4, 5, 7]

What a finished answer prints, from the lesson. Nothing has run yet — press Run and this is replaced by your program’s own output.
