Add and Multiply

The goal here is simple: given two numbers $a$ and $b$, you need to print $a+b$ and $a*b$. ###Input: - First line will contain $T$, number of testcases. Then the testcases follow. - Each testcase contains of a single line of input, two integers $a, b$. ###Output: For each testcase, output in a single line, first $a+b$, then $a*b$, separated by a space. ###Constraints: - $1 \leq T \leq 10^5$
