sum_max_min

#3876

Se dă un șir de N numere întregi. Pentru fiecare subșir nevid al șirului dat se consideră valoarea întreagă D egală cu diferența dintre elementul maxim și cel minim aflat în subșir. Să se afle suma valorilor D ale tuturor subșirurilor nevide, mai mici sau egale decât un număr întreg T dat modulo \( {10}^{9} + 7 \).
