Cairo City is a metropolis with Nβ‹…MN\cdot M public transport stations, where N,Mβ‰₯3N,M\ge 3. The stations are arranged in NN concentric circles, and there are MM stations over each circle. The circles are numbered from 00 to Nβˆ’1N-1, and for each circle, the stations are numbered from 00 to Mβˆ’1M-1, inclusive. We refer to station jj on circle ii as station (i,j)(i,j) (where i=0…Nβˆ’1i=0 \ldots N-1, j=0…Mβˆ’1j=0 \ldots M-1).

In the city, there are NN tram lines. Tram lines are bidirectional and periodic, each connecting consecutive stations of some circle. Let tram line kk (where k=0…Nβˆ’1k=0 \ldots N-1) connect the stations on circle kk, i.e., stations (k,0)…(k,Mβˆ’1)(k,0) \ldots (k,M-1). Station (k,Mβˆ’1)(k,M-1) is connected with station (k,0)k,0).

Additionally, there are MM metro lines in the city. Metro lines are bidirectional, each connecting consecutive stations at the same position over different circles. Let metro line ll (where l=0…Mβˆ’1l=0 \ldots M-1) connect stations at position ll on each circle, i.e., stations (0,l)…(Nβˆ’1,l)(0,l) \ldots (N-1,l). Stations (Nβˆ’1,l)(N-1,l) and(0,l)(0,l) are not connected.


The figure shown above is the transport network for N=3N=3 and M=6M=6, having S0=1,S1=2,S2=3S_0=1, S_1=2, S_2=3 and T0=1,T1=5T_0=1, T_1=5.

Traveling between consecutive stations via tram line kk takes SkS_k minutes (where k=0…Nβˆ’1k=0 \ldots N-1). For each metro line ll (where l=0…Mβˆ’1l=0 \ldots M-1), traveling between stations (i,l)(i,l) and (i+1,l)(i+1,l) takes TiT_i minutes (where i=0…Nβˆ’2i=0 \ldots N-2).

Your task is to determine shortest travel times in this public transport network. You are given QQ queries, each query specifies two public transport stations (Aq,Bq)(A_q,B_q) and (Cq,Dq)(C_q,D_q) (where q=0…Qβˆ’1q=0 \ldots Q-1). For each query, find the minimum amount of time it takes to get from the first station to the second one, assuming that changing lines doesn't take extra time.

Input data

The first line contains integers NN, MM and QQ. The second line contains NN integers SkS_k. The third line contains Nβˆ’1N-1 integers TiT_i.

Each of the next QQ lines contains four integers Aq,Bq,CqA_q, B_q, C_q and DqD_q.

Output data

For each query, output a single number on a separate line, the minimum travel time (in minutes) between the specified stations.

Explanation

The public transport network in the sample case is displayed in the figure above.

In the first query, the minimum time to reach station (1,5)(1,5) from (1,2)(1,2) is 55 minutes, e.g., by taking the path
(1,2)βˆ’(0,2)βˆ’(0,3)βˆ’(0,4)βˆ’(0,5)βˆ’(1,5)(1,2) - (0,2) - (0,3) - (0,4) - (0,5) - (1,5).

In the second query, the minimum time to reach station (2,4)(2,4) from (2,1)(2,1) is 99 minutes, e.g., by taking the path
(2,1)βˆ’(2,0)βˆ’(2,5)βˆ’(2,4)(2,1) - (2,0) - (2,5) - (2,4).
