You are given $N$ pairs of integers: $(A_1, B_1), (A_2, B_2), \ldots, (A_N, B_N)$. For each $i = 1, 2, \ldots, N$, print $A_i + B_i$.

The input is given from Standard Input in the following format:

```
$N$
$A_1$ $B_1$
$A_2$ $B_2$
$\vdots$
$A_N$ $B_N$
```

Print $N$ lines. For $i = 1, 2, \ldots, N$, the $i$\-th line should contain $A_i+B_i$.

-   $1 \leq N \leq 1000$
-   $-10^9 \leq A_i, B_i \leq 10^9$
-   All values in the input are integers.

The first line should contain $A_1+B_1=3+5=8$.
The second line should contain $A_2+B_2=2+(−6)=−4$.
The third line should contain $A_3+B_3=(−5)+0=−5$.
The fourth line should contain $A_4+B_4=314159265+123456789=437616054$.
