# Statement Title
Given two integers $a$ and $b$. Compute $a+b$.
## Implementation Details
You should implement the following procedure:
```
int plus (int a, int b)
```
- $a,b$: two integers.
This procedure should return the sum of $a$ and $b$.
## Examples
### Example 1
Consider the following call:
```
plus (3, 5)
```
$3+5=8$, so the procedure should return $8$.

## Constraints
- $1 \leq a, b \leq 10^9$
## Subtasks
1. (30 points) $a,b \leq 10$
2. (70 points) no additional constraints.
## Sample Grader
The sample grader will read the input in the following format:
- line $1$: $a\ b$
The output of the sample grader is in the following format:
- line $1$: the return value of `plus`
