Some Number

This version of the problem differs from the next one only in the constraint on $$$t$$$. You can make hacks only if both versions of the problem are solved.

You are given two positive integers $$$l$$$ and $$$r$$$.

Count the number of distinct triplets of integers $$$(i, j, k)$$$ such that $$$l \le i < j < k \le r$$$ and $$$\operatorname{lcm}(i,j,k) \ge i + j + k$$$.

Here $$$\operatorname{lcm}(i, j, k)$$$ denotes the least common multiple (LCM) of integers $$$i$$$, $$$j$$$, and $$$k$$$.

Input

Each test contains multiple test cases. The first line contains the number of test cases $$$t$$$ ($$$\bf{1 \le t \le 5}$$$). Description of the test cases follows.

The only line for each test case contains two integers $$$l$$$ and $$$r$$$ ($$$1 \le l \le r \le 2 \cdot 10^5$$$, $$$l + 2 \le r$$$).

Output

For each test case print one integer — the number of suitable triplets.

Note

In the first test case, there are $$$3$$$ suitable triplets:

  • $$$(1,2,3)$$$,
  • $$$(1,3,4)$$$,
  • $$$(2,3,4)$$$.

In the second test case, there is $$$1$$$ suitable triplet:

  • $$$(3,4,5)$$$.
