<p>Trans bought a calculator at creatnx's store. Unfortunately, it is fake. It has many bugs. One of them is adding two numbers without carrying. Example expression: 12 + 9 will have result 11 in his calculator. Given an expression in the form <b>a + b</b>, please output result from that calculator.</p>
<p> </p>


<h3>Input</h3>
<p>The first line contains an integer <b>T</b> denote the number of test cases. Each test case contains two integers <b>a, b</b> in a single line.</p>
<p> </p>

<h3>Output</h3>
<p>Each test case, print answer in a single line.</p>
<p> </p>

<h3>Constraints</h3>
<ul>
<li><b>1 ≤ T ≤ 100</b></li>
<li><b>1 ≤ a, b ≤ 10<sup>9</sup></b></li>
</ul>
<p></p>
<p>Subtasks:</p>
<ul>
<li>Subtask #1 (30 points): <b>1 ≤ a, b ≤ 9</b></li>
<li>Subtask #2 (70 points): original constrains</li>
</ul>
<p> </p>
