Variant 8.1.4. Dima and Seryozha were picking berries from a raspberry bush, on which 450 berries grew. Seryozha alternated actions while picking berries: he put one berry in the basket and ate the next one. Dima also alternated: he put two berries in the basket and ate the next one. It is known that Seryozha picks berries twice as fast as Dima. At some point, the boys had picked all the raspberries from the bush.

Who of them ended up putting more berries in the basket? What will the difference be?
