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.

Example

Solution (in PYTHON3):

Solution:
t = int(input())

for _ in range(t):
    a, b, q = map(int, input().split())
    lcm = a * b

    table = [0] * lcm

    for i in range(1, lcm):
        if ((i % a) % b) != ((i % b) % a):
            table[i] = table[i - 1] + 1
        else:
            table[i] = table[i - 1]

    answers = []

    for _ in range(q):
        x, y = map(int, input().split())

        lcmsInside = (y // lcm) - (x // lcm)
        t = lcmsInside * table[-1]

        x = x % lcm
        y = y % lcm

        if x != 0:
            t -= table[x - 1]

        t += table[y]

        answers.append(t)

    print(*answers)
