我个人测试无误，洛谷IDE也通过了，请教大佬为什么RE了

dict_pw = {chr(65 + i): '0' for i in range(26)}
error = True
sum =0

str_1 = input()
str_2 = input()
str_3 = input()
len_str_pw = len(str_1)
len_str_new = len(str_3)

for i in range(len_str_pw):
    if dict_pw[str_1[i]] == '0':
       dict_pw[str_1[i]] = str_2[i]
       sum += 1
    elif dict_pw[str_1[i]] == str_2[i]:
        continue
    else:
        error = False
        break
if sum != 26:
    error = False

if error:
    for i in range(len_str_new):
        print(dict_pw[str_3[i]], end="")
else:
    print('Failed')
