如圖 使用unk_403040處的資料執行switch 並且最後的對比資料也在這裡面

我們把switch用的資料和對比資料提取出來

[10, 4, 16, 8, 3, 5, 1, 4, 32, 8, 5, 3, 1, 3, 2, 8, 11, 1, 12, 8, 4, 4, 1, 5, 3, 8, 3, 33, 1, 11, 8, 11, 1, 4, 9, 8, 3, 32, 1, 2, 81, 8, 4, 36, 1, 12, 8, 11, 1, 5, 2, 8, 2, 37, 1, 2, 54, 8, 4, 65, 1, 2, 32, 8, 5, 1, 1, 5, 3, 8, 2, 37, 1, 4, 9, 8, 3, 32, 1, 2, 65, 8, 12, 1]
[
 
34, 63, 52, 50, 114, 51, 24, 167, 49, 241, 40, 132, 193, 30, 122]

可以發現 input的每一位都是單獨處理的 遇到1就換下一位 所以我們可以倒敘處理對比資料得到input

f = open('so.in')
a = []
for i in range(21):
    s = f.readline()
    for j in range(16):
        if j % 4 == 0:
            a.append(int(s[j*3:j*3+2],16))
print a
b = []
for i in range(7):
    s 
 
= f.readline()
    for j in range(16):
        if j ==4  or j ==12 :
            b.append(int(s[j*3:j*3+2],16))
b.append(0x7a)
print b
v5 = 0
v3 = 0
v9 = 14
flag = ''
for i in range(len(a)-1,-1,-1):
    if i == 0:
        flag += chr(v3)
    if a[i] == 1 and a[i-1] != 1 :
        v5 = b[v9]
        v9 = v9 - 1
        flag 
 
+= chr(v3)
    elif a[i] == 2 and a[i-1] != 3 and a[i-1] != 4 and a[i-1] != 5:
        v3 = v5 - a[i+1]
    elif a[i] == 3 and a[i-1] != 2 and a[i-1] != 4 and a[i-1] != 5:
        v3 = v5 + a[i+1]
    elif a[i] == 4 and a[i-1] != 3 and a[i-1] != 2 and a[i-1] != 5:
        v3 = v5 ^ a[i+1]
    elif a[i] == 5 and a[i-1] != 3 and a[i-1] != 4 and a[i-1] != 2:
        v3 = v5 // a[i+1]
    elif a[i] == 8:
        v5 = v3
    elif a[i] == 11:
        v3 = v5 + 1
    elif a[i] == 12:
        v3 = v5 - 1
print flag[::-1]
