### BUGGY CODE ###

C = list(map(int, input().split()))
S = [list(map(int, input().split())) for _ in range(D)]
T = [int(input()) for _ in range(D)]

M = int(input())

for i in range(M):
    res = 0
    last = [0 for _ in range(26)]
    T[Q[i][0] - 1] = Q[i][1]
    for d in range(D):
        res += S[d][T[d] - 1]
        last[T[d] - 1] = d + 1
        for j in range(26):
            res -= C[j] * ((d + 1) - last[j])
    print(res)
