不想谈太多，这种写算法的题对我来说太过致命，要多练这种题，直接上代码

a = [0x5F, 0xF2, 0x5E, 0x8B, 0x4E, 0x0E, 0xA3, 0xAA, 0xC7, 0x93,

0x81, 0x3D, 0x5F, 0x74, 0xA3, 0x09, 0x91, 0x2B, 0x49, 0x28,

0x93, 0x67, 0x00, 0x00]

flag = []

for i in range(22):

    `temp = 00`

   ` for j in range(i+1):`

            `temp = 1828812941 * temp + 12345`

    `print(chr((temp^a[i])&0xff))`

# flag[i] = (temp^a[i])&0xff

#print(''.join(map(chr,flag)))
