As everyone knows, the university where Kruskal-chan studies is USTC. Now, Kruskal-chan would like to test you: what could USTC stand for? I believe you can provide a brilliant answer.

You need to output a string whose acronym could be USTC.

The definition of an acronym is as follows:

• An acronym is a new word formed by taking the first letter of each word in a phrase.
• The first letter of content words in the original phrase must be capitalized, while the first letter of function words must be lowercase; all other letters must be lowercase.
• For all content words, their first letter must be preserved.
• For all function words, you may choose to preserve their first letter and capitalize it, depending on the situation.

Output a single line containing a string with spaces, whose acronym could be USTC. As long as your output has an acronym that is USTC, it is considered correct.
