Problem B
Summing Integers

Write a program using a while statement, that given a series of numbers as input, adds them up until the input is $10$ and then prints the total. Without adding the final $10$.

Input

Input consists of $n$ lines, where $1 \leq n \leq 1\, 000$. The $i$th line contains one integer $a_i$, where $0 \leq a_i \leq 100$. It is guaranteed that $a_n = 10$.

Output

Output consists of one line with one integer, the sum of the numbers given excluding the final $10$.
