题目描述
You are given a sequence $A_1, A_2, \ldots, A_N$. Calculate the number of ways to remove a non-empty contiguous subsequence from it such that the resulting sequence is non-empty and strictly increasing.
-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first line of each test case contains a single integer $N$.
- The second line contains $N$ space-separated integers $A_1, A_2, \ldots, A_N$.
-----Output-----
For each test case, print a single line containing one integer ― the number of ways.
-----Constraints-----
- $1 \le T \le 10$
- $1 \le N \le 10^5$
- $|A_i| \le 10^9$ for each valid $i$
-----Subtasks-----
Subtask #1 (40 points): $N \le 1,000$
Subtask #2 (60 points): original constraints
