20分代码，帮忙看一下出了啥问题
n = int(input())
marks = {}
zuoxia = []
youshang = []
for i in range(n):
f_info = list(map(int, input().split()))
zuoxia.append((f_info[0], f_info[1]))
youshang.append((f_info[0] + f_info[2], f_info[1] + f_info[3]))
ans_m = tuple(map(int, input().split()))
ans = 0
for i in range(0, n):
if zuoxia[i][0] <= ans_m[0] <= youshang[i][0]:
if zuoxia[i][1] <= ans_m[1] <= youshang[i][1]:
ans += 1
if ans == 0:
print(-1)
else:
print(ans)
