Saturate

#4630

Se dă un graf neorientat cu n vârfuri și m muchii. Se numește vârf saturat un vărf care are gradul mai mare sau egal cu jumatatea numărului de vărfuri. Dacă numărul de vărfuri este impar, atunci gradul trebuie să fie mai mare strict decăt jumătatea numărului de vărfuri. Să se afișeze vârfurile saturate din graful dat.
