用 chatgpt 翻译一下字节码.

flag = [204, 141, 44, 236, 111, 140, 140, 76, 44, 172, 7, 7, 39, 165, 70, 7, 39, 166, 165, 134, 134, 140, 204, 165, 7, 39, 230, 140, 165, 70, 44, 172, 102, 6, 140, 204, 230, 230, 76, 198, 38, 175]

for i in range(42):
    flag[i] = (flag[i] >> 5) | (flag[i] << 3) & 255

print(''.join(chr(x) for x in flag))
# flag{ddbae889-2895-44df-897d-2ae30df77b61}
