Description

’Why are you always repeating what I say?’ says Applese, a friend of Little Sub.

’Because it is the most important quality of mankind.’ says Little Sub.

Now it is your turn to repeat what Applese says.

Generally, each sentence Applese says will only contains ’A’..’Z’, ’a’..’z’, ’0’..’9’, space, ’!’ and ’.’.

Each sentence will definitely end with either ’!’ or ’.’. If it ends with ’.’, change it to ’!’ instead.

Applese has just passed his 17th birthday, we wish him and his friends very good luck in the future study and programming competitions.
