Chạy bình thường ở bên ngoài nhưng vào Themis chấm lại bị lỗi

[Minh_Syrex (Minh)]

Cho e hỏi lỗi như dưới đây là gì và sửa như nào ạ
Đề bài đây ạ:

Code:

f=open('olympic.inp','r')
g=open('olympic.out','w')
n,m=map(int,f.readline().split())
s=[int(x) for x in f.readline().split()]
b=[]
period=[[0,0,0]]
for i in range(m):
    b.append([int(x) for x in f.readline().split()])
for i in range(n):
    prev=period[i].copy()
    if s[i]==1:prev[0]+=1
    elif s[i]==2:prev[1]+=1
    else:prev[2]+=1
    period.append(prev)

for i in b:
    g.write(f'{period[i[1]][0]-period[i[0]-1][0]} {period[i[1]][1]-period[i[0]-1][1]} {period[i[1]][2]-period[i[0]-1][2]}\n')
f.close()
g.close()
