總結:
1.這個演算法很簡單,而且有兩位的演算法是一樣就是U1跟U6,U2跟U5,U3跟U4.
2.下面我不算式列出來:(用A1-->A6代表給位的總和)
A1=U1*29A
A6=U6*29A
A2=U2+(U2+(U2+(U2*10+U2)*4)*4)*2
A5=U5+(U5+(U5+(U5*10+U5)*4)*4)*2
A3=((U3*8-U3)*10-U3)*4
A4=((U4*8-U4)*10-U4)*4
3.舉例:
NAME:ssljxccc(其實演算法要六位就夠了..我輸入多兩位..)
s=73 s=73 l=6c j=6a x=78 c=63
A1=73*29A=12B2E
A2=73+(73+(73+(73*10+73)*4)*4)*2=F951
A3=((6C*8-6C)*10-6C)*4=BB50
A4=((6A*8-6A)*10-6A)*4=B7D8
A5=78+(78+(78+(78*10+78)*4)*4)*2=10428
A6=63*29A=1018E
註冊嗎:A1+A2+A3+A4+A5+A6=12B2E+F951+BB50+B7D8+10428+1018E=59D5D
換算成十進位制:367965 完成..
