这个没有入口,只能一个个看,发现qes这个函数有一堆数,函数很小,逆向也容易,找到然后用BJD包裹
#int qes()
a = [0x7FFA7E31,0x224FC,0x884A4239,0x22A84,0x84FF235,0x3FF87,0x88424233,0x23185,0x7E4243F1,0x231FC]
for i in range(5):
v6 = (a[i*2] & 0xffffffff) | ((a[i*2+1] & 0xffffffff)<<32)
v2 = [0]*51
v8 = 0
while v6:
v2[v8] = v6%2
v6 >>=1
v8 +=1
for j in range(50,-1,-1):
if v2[j] == 1:
print('*', end='')
else:
print(' ', end='')
if j%5 == 0:
print(' ', end='')
print('')
