Problem: You are given two integers a and b, and q queries. The i-th query consists of two numbers l_i and r_i, and the answer to it is the number of integers x such that l_i ≤ x ≤ r_i, and ((x mod a) mod b) ≠ ((x mod b) mod a). Calculate the answer for each query.

Recall that y mod z is the remainder of the division of y by z. For example, 5 mod 3 = 2, 7 mod 8 = 7, 9 mod 4 = 1, 9 mod 9 = 0.

Input

The first line contains one integer t (1 ≤ t ≤ 100) — the number of test cases. Then the test cases follow.

The first line of each test case contains three integers a, b and q (1 ≤ a, b ≤ 200; 1 ≤ q ≤ 500).

Then q lines follow, each containing two integers l_i and r_i (1 ≤ l_i ≤ r_i ≤ 10^{18}) for the corresponding query.

Output

For each test case, print q integers — the answers to the queries of this test case in the order they appear.

Solution:
import sys
t = int(input())
for q in range(t):
    a, b, q = map(int,input().strip().split())
    ans = []
    grid = []
    for i in range(a*b+1):
        if i == 0:
            grid.append(0)
        else:
            grid.append(grid[i-1] + ((i%a)%b != (i%b)%a))
    for i in range(q):
        l, r = map(int,input().strip().split())
        l -= 1
        ans1 = grid[a*b]*(r//(a*b)) + grid[r%(a*b)]
        ans2 = grid[a*b]*(l//(a*b)) + grid[l%(a*b)]
        ans.append(ans1-ans2)
    print(*ans)
