[Chinese statement](https://www.luogu.com.cn/problem/P11243). **You must submit your code at the Chinese version of the statement.** I've already known. Known at the time when I set up the loop playback. That, I was numbing myself and avoiding the problem. I admitted it, but when picking up those details that sank underwater, I suddenly resonated with all those real heartbeats in an instant. Then I always thought too little while now I often think too much, at a loss like green algae spreading in a deserted pond. In the world were too many emotions; nevertheless, Iris could only tell happier or sadder.

Iris wants to look into the question. She wants to do some statistics first; therefore, she abstracts the following problem. Iris has $n$ unknowns $a_1\dots a_n$. For each $1 \leq i < n$, she has compared $a_i$ and $a_{i+1}$ and written a character $c_i \in \{\texttt{>}, \texttt{$, then $a_i > a_{i+1}$; - If $c_i = \texttt

- In the first sample test case, one can see that $a_i$ is happier than $a_j$ if and only if $1 \leq i < j \leq n$, so there are a total of $\frac{5\times 4}{2} = 10$ pairs $(i, j)$. - In the second sample test case, the $9$ pairs are listed as follows: $(1, 2), (1, 3), (4, 2), (4, 3), (4, 5), (4, 6), (4, 7), (5, 7), (6, 7)$. - For the rest of the test cases, clever readers can verify that for themselves.
