Problem Statement

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 $A_i + B_i$.

Constraints

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

Input

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

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

Output

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

• 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 $A_4 + B_4 = 314159265 + 123456789 = 437616054$.
