#3286

Fișierul nrnot.in conține pe prima linie un număr natural n (\( n \in [2,10^7] \)) , iar pe următoarele linii un șir de cel mult 1000 numere naturale din intervalul [1,n]. Numerele sunt ordonate descrescător și sunt separate prin câte un spațiu. Se cere să se determine numărul valorilor naturale distincte din intervalul [1,n] care NU se găsesc în șir.
