Problem: Amugae is in a very large round corridor. The corridor consists of two areas. The inner area is equally divided by n sectors, and the outer area is equally divided by m sectors. A wall exists between each pair of sectors of same area (inner or outer), but there is no wall between the inner area and the outer area. A wall always exists at the 12 o'clock position.

<image>

The inner area's sectors are denoted as (1,1), (1,2), ..., (1,n) in clockwise direction. The outer area's sectors are denoted as (2,1), (2,2), ..., (2,m) in the same manner. For a clear understanding, see the example image above.

Amugae wants to know if he can move from one sector to another sector. He has q questions.

For each question, check if he can move between two given sectors.

Input

The first line contains three integers n, m and q (1 ≤ n, m ≤ 10^{18}, 1 ≤ q ≤ 10^4) — the number of sectors in the inner area, the number of sectors in the outer area and the number of questions.

Each of the next q lines contains four integers s_x, s_y, e_x, e_y (1 ≤ s_x, e_x ≤ 2; if s_x = 1, then 1 ≤ s_y ≤ n, otherwise 1 ≤ s_y ≤ m; constraints on e_y are similar). Amague wants to know if it is possible to move from sector (s_x, s_y) to sector (e_x, e_y).

Output

For each question, print "YES" if Amugae can move from (s_x, s_y) to (e_x, e_y), and "NO" otherwise.

You can print each letter in any case (upper or lower).

Example

Input


4 6 3
1 1 2 3
2 6 1 2
2 6 2 4


Output


YES
NO
YES
