#3212

Se apropie Crăciunul. Gigel a văzut la magazin trei jucării care îi plac: cel mai mult îi place o dronă, care costă d lei, apoi îi place un robot care costă r lei, apoi o mașină care costă m lei, d > r > m. De Crăciun Gigel merge la colindat la rude și va primi de la acestea S lei. Aflați ce jucărie va cumpăra Gigel cu banii câștigați: drona, robotul, masina sau niciuna dintre ele!
