Overtaking method based on sand-sifter mechanism: Why …
The hole of the sand-sifter on the upper side is larger than one on the lower side. We drop k pebbles into the top of the piled sand-sifters. The pebbles are wrapped by soil. The soil is scraped off through the piled sand-sifters, and the smaller pebble drops down. The largest pebble is left on the top of the sand-sifters, and we can pick it up.
