Du bronze pour la Suisse aux Olympiades Internationales d’Informatique en Italie

 IOI12_Marco.jpg Marco Keller (Kantonsschule Wil) de Kirchberg SG a gagné une médaille de bronze pour la Suisse lors des Olympiades Internationales d’Informatique 2012 (IOI) à Sirmione (Italie). Les 300 jeunes doués pour l’informatique ont dû solutionner six devoirs de programmation épineux durant deux jours de compétition. Marco Keller s’est surtout distingué lors d’un problème particulièrement difficile à résoudre où il a obtenu une spectaculaire 5e place, laissant derrière lui pratiquement toute la concurrence internationale, dont les Chinois, un véritable exploit.
