Input Scandal

Inputte is solving their first problems Kattis. Most of the problems Inputte have solved so far has been relatively easy, since the number of input rows is always clearly stated in the problem.

One day, Inputte was trying a whole new problem. The problem had an unknown amount rows of input. Inputte had no clue how to read the input without taking too little or too much.
