Se dă un şir format din N numere naturale nenule. Spunem că un număr e fericit dacă se poate scrie ca suma pătratelor a două numere naturale. Notăm cu K numărul numerelor fericite din şir şi cu P produsul acestora. Aflaţi numărul K precum şi două numere naturale care au suma pătratelor egală cu PE, unde E este un număr natural dat.
