Harta3

#4155

Harta unei regiuni este reprezentată într-un sistem de coordonate cartezian și sunt cunoscute coordonatele a n orașe, numerotate de la 1 la n.

Se dorește construirea unor drumuri bidirecționale între anumite perechi de orașe, astfel încât:

• să se poate ajunge din orice oraș în oricare altul folosind unul sau mai multe dintre drumurile construite;
• suma lungimilor drumurilor construite să fie minimă.

Să se determine suma lungimilor drumurilor construite.
