A pair of positive integers $(a,b)$ is called special if $\lfloor \frac{a}{b} \rfloor = a mod b$. Here, $\lfloor \frac{a}{b} \rfloor$ is the result of the integer division between $a$ and $b$, while $a mod b$ is its remainder.

You are given two integers $x$ and $y$. Find the number of special pairs $(a,b)$ such that $1\leq a \leq x$ and $1 \leq b \leq y$.


-----Input-----

The first line contains a single integer $t$ ($1 \le t \le 100$) — the number of test cases.

The only line of the description of each test case contains two integers $x$, $y$ ($1 \le x,y \le 10^9$).


-----Output-----

For each test case print the answer on a single line.


-----Examples-----

Input
9
3 4
2 100
4 3
50 3
12 4
69 420
12345 6789
123456 789
12345678 9
Output
1
0
2
3
5
141
53384
160909
36


-----Note-----

In the first test case, the only special pair is $(3, 2)$.

In the second test case, there are no special pairs.

In the third test case, there are two special pairs: $(3, 2)$ and $(4, 3)$.
