CF1140B Good String

Description

You have a string $ s $ of length $ n $ consisting of only characters > and , the character that comes right after it is deleted (if the character you chose was the last one, nothing happens). If you choose a character in string > > < >, the string will become to > > >. And if we choose character < in string > > are good. Before applying the operations, you may remove any number of characters from the given string (possibly none, possibly up to $ n - 1 $ , but not the whole string). You need to calculate the minimum number of characters to be deleted from string $ s $ so that it becomes good.

Input Format

The first line contains one integer $ t $ ( $ 1 \le t \le 100 $ ) – the number of test cases. Each test case is represented by two lines. The first line of $ i $ -th test case contains one integer $ n $ ( $ 1 \le n \le 100 $ ) – the length of string $ s $ . The second line of $ i $ -th test case contains string $ s $ , consisting of only characters > and

Output Format

For each test case print one line. For $ i $ -th test case print the minimum number of characters to be deleted from string $ s $ so that it becomes good.

Explanation/Hint

In the first test case we can delete any character in string . In the second test case we don't need to delete any characters. The string > < < is good, because we can perform the following sequence of operations: > < < $ \rightarrow $ < < $ \rightarrow $
