Compute (a+b)/c

Problem Background

Special for beginners, ^_^

Problem Description

Given $3$ integers $a, b, c$, compute the value of the expression $(a+b)/c$, where $/$ denotes integer (truncating) division.

Input Format

A single line containing three integers $a, b, c$, separated by single spaces. ($-10,000 \lt a,b,c \lt 10,000$, and $c$ is not $0$.)

Output Format

A single line: the value of the expression.

Sample Input

1 1 3

Sample Output

0

Hint

• Think: when two int values are divided, what type is the result? This problem wants exactly that result — don't rush to convert to double.
• Check against the sample: 1 1 3 → 0.

Note: In C/C++, integer division truncates by default, i.e. the fractional part is simply discarded — equivalently, it is the integer part of the quotient of the two numbers.
