Interactive sum

This is a test interactive problem. You have to add two integers $n$ times interactively.

Interaction

The first line of inputs contains a single integer $n$ ($1\le n\le 10^5$). Each of the following $n$ lines contains two integers $a$ and $b$ ($0\le a,b\le 10^5$). For each pair, print the sum of $a$ and $b$. You will get next query only after you answer the previous one.

Please do not forget to flush the buffer, otherwise you may get Idleness limit exceeded.

• fflush(stdout) or cout.flush() in C++;

• System.out.flush() in Java;

• flush(output) in Pascal;

• stdout.flush() in Python;

• Refer to the documentation in other languages.
