The difference between us is that I was trying to solve it inside the brain without trying on and it didn't work. E.g. we just have different approaches. I usually try every problem inside the brain first. If it's my own problem, then I may try some experiments after I have an idea of solution. In this particular case I gave up immediatelly after solving it inside the brain with the loop and disregarding this option like not a good one.
