Sum only scores within the inclusive interval $[0,10]$ among $n$ integers. Ignore values below 0 or above 10. Both endpoints are valid; print 0 if no value qualifies.

Subtasks

• Subtask 1 (20%): $0\le n\le 8$; $-100\le a_i\le100$.

• Subtask 2 (30%): $0\le n\le 1000$; $-100\le a_i\le100$.

• Subtask 3 (50%): $0\le n\le 100000$; $-100\le a_i\le100$.
