Fibonotci sequence is an integer recursive sequence defined by the recurrence relation Sequence s is an infinite and almost cyclic sequence with a cycle of length N. A sequence s is called almost cyclic with a cycle of length N if , for i ≥ N, except for a finite number of values si, for which (i ≥ N). Following is an example of an almost cyclic sequence with a cycle of length 4: Notice that the only value of s for which the equality does not hold is s6 (s6 = 7 and s2 = 8). You are given s0, s1, ...sN - 1 and all the values of sequence s for which (i ≥ N). Find . The first line contains two numbers K and P. The second line contains a single number N. The third line contains N numbers separated by spaces, that represent the first N numbers of the sequence s. The fourth line contains a single number M, the number of values of sequence s for which . Each of the following M lines contains two numbers j and v, indicating that and sj = v. All j-s are distinct. Output should contain a single integer equal to .
