Scadere

#1220

Fie n un număr natural nenul.

Să considerăm o expresie de forma: x[1]-x[2]-x[3]-...-x[n]

Se ştie că scăderea nu este o operaţie asociativă, adică x[1]-(x[2]-x[3])≠(x[1]-x[2])-x[3].

Ca urmare, prin plasarea unor perechi de paranteze în expresie, putem obţine diferite valori.
Pentru problema noastră, vom denumi scădere o expresie de forma de mai sus în care pot apărea şi paranteze rotunde care se închid corect. Valoarea unei scăderi se obţine efectuând operaţiile de scădere în ordine de la stânga la dreapta; dacă apar paranteze, se efectuează mai întâi operaţiile din paranteze.

Date fiind valorile x[1], x[2], …, x[n] care intervin în scădere, scrieţi un program care să rezolve următoarele două cerinţe:

1. să se determine valoarea maximă a unei scăderi (obţinută prin inserarea convenabilă a unor paranteze rotunde în expresia x[1]-x[2]-x[3]-...-x[n]), precum şi o scădere având valoare maximă.
2. să se determine valoarea unei scăderi specificate.
