PTA 7-68 Redemption

I am dreadfully sorry for your bad experience, such a low number of submissions as well as pass rates and my

in SHI ZHAN YI.

I set up some challenging data points and some a littlt bit hard problems. If you are interested in them, you can try to solve them. If not, that's also OK. In other words, that will NOT affect your score. Do NOT worried about them. Please take it step by step and please remember, it is really important for you to learn how to study by yourself.

Finally, I am so sorry...

Remarkably HANDSOME _October has warned me to reduce the difficulty of the problems. So there you just need to output "HEIlO, W0RLD！"（without quotation marks）
