A+B for Input-Output Practice(VIII)
描述
Your task is to calculate the sum of some integers
输入
Input contains an integer N in the first line, and then N lines follow.
Each line starts with a integer M, and then M integers follow in the same line
输出
For each group of input integers you should output their sum in one line,
and you must note that there is a blank line between outputs.
