A+B for Input-Output Practice (V)

   寒假了，弱鸡也要开始做题了，其实自己做过的题目不少，但都没留下什么wp。原本觉得没什么，但时间一长，发现自己很多题目都记不清了，这与没做已经没什么区别了，所以决定从今天起把做过的和新题目都回顾一遍。

   这是一道我入门时做的题目，先审题

Input

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.
