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 (in PYTHON3):

Solution:
tc = int(input())


def build(a, b):
    m = [0] * (a * b)
    for i in range(a * b):
        if i % a % b != i % b % a:
            m[i] = 1
    for i in range(1, len(m)):
        m[i] += m[i - 1]
    return m


def solve(l, m):
    s = m[-1] * (l // len(m))
    return s + m[l % len(m)]

for _ in range(tc):
    a, b, q = map(int, input().split())
    m = build(a, b)
    ans = []
    for _ in range(q):
        l, r = map(int, input().split())
        ans.append(solve(r, m) - solve(l - 1, m))
    print(' '.join(map(str, ans)))
