Problema #1651 GRAF de pe Pbinfo Cerința
Se dă lista muchiilor unui graf neorientat ponderat. Să se determine vârful pentru care media aritmetică a ponderilor muchiilor incidente este minimă. Dacă există mai multe vârfuri cu aceeași medie minimă, se va afișa vârful numerotat cu o valoare mai mică.

Date de intrare
Programul citește de la tastatură numerele n m, reprezentând numărul de vârfuri și numărul de muchii din graf, apoi m triplete i j p, reprezentând muchiile, date prin extremități și pondere.

Date de ieșire
Programul va afișa pe ecran numărul vf, reprezentând vârful determinat.

Restricții și precizări
1 ≤ n ≤ 100
ponderile muchiilor sunt numere naturale nenule mai mici decât 1000

Explicație
Mediile ponderilor muchiilor incidente cu vârfurile grafului sunt:

pentru vârful 1 media este 10
pentru vârful 2 media este 4.66667
pentru vârful 3 media este 5
pentru vârful 4 media este 3
pentru vârful 5 media este 6.33333
Astfel media minimă este 3, pentru vârful 4
