Recently, Colin found that DeepSeek is such a useful AI that he can always give it problems he meets and receive lots of good suggestions, especially when Colin turns on the DeepThink option: DeepSeek will show the procedure of thinking, and it makes everything look so clear and convincing!

Although DeepSeek's thinking procedure does look like a human's, Colin found a phenomenon that always starts with, "Okay, so I want to figure out how to..."

Colin wants to build an extraordinary AI by himself: ColinSeek, but since Colin knows too little about AI, he decides to start by imitating. Now, please help Colin write the very first code for the ColinThink option of ColinSeek:

When the user asks in the format How to xxx?, show the thinking procedure as Okay, so I want to figure out how to xxx. The last part (xxx) is the same as the user's question.

Input

A single line represents the user's question. The input is guaranteed to start with "How to "$$$~$$$and end with "?". The input between these two parts consists of lower English letters, digits, and blank spaces. Except for the two sample inputs, the length of the input line (excluding the line ending) is larger than 1024 bytes and less than 16384 bytes.

Output

Output the thinking procedure of ColinSeek, as described in the description.
