We have a pair of balances and every time we can choose an even number of coins and put half of them on one side of the balance and put another half on the other side, therefore a comparison will be done.
Oleme paari saldod ja iga kord saame valida ka müntide arvu ja pane pooled neist ühel küljel tasakaalu ja pane teine pool teisel pool, seega võrdlemine toimub.
