"Rearranging code blocks" - How do I do this?

Question

I'm new here. Sorry if I'm asking a dumb question.
The form says "Rearrarange the code blocks to form a valid c++ program".
It has 5 lines in the wrong order. How do rearrange the order of the blocks? Cut, copy and paste; nope.

The answer should be:
#include <iostream>
using namespace std;
lnt main() {
cout << "Hello world!"; return 0;
}

I have an "Acer - R 11 CB5-132T-C8ZW 2-in-1 11.6" Touch-Screen Chromebook - Intel Celeron - 4GB Memory - 16GB eMMC Flash Memory - White", which works pretty well under Chromium so far.

Thanks for your help.

Tap on the blocks and try to move up and down to rearrange, it should work :) Just like drag and drop.
