三、算法小结
1.注册码形式：****-****-**** (P1-P2-P3)
2.Login(E-Mail):wzwgp@163.com (0X 777A776770403136332E636F6D)
计算方法是常数加上字符的16进制值与下标乘积之和
P1计算E-Mail的第一个字符到"@"(含@)
s1=D7A(常数)
P1=s1+(77*1)+(7A*2)+(77*3)+(67*4)+(70*5)+(40*6)=1596
转成10进制：P1=5526
P2计算E-Mail从字符"@"(含@)开始，计算字符个数是"@"和"."之间的字符个数值
s2=1CB4(常数)
P1=s2+(40*6)+(31*7)+(36*8)=213B
转成10进制：P2=8507
P3计算E-Mail字符的开始位置是E-Mail字符个数减"."后的字符个数与2之和
s3=10E9(常数)
P3=s3+(36*8)+(33*9)+(2E*A)+(63*B)+(6F*C)+(6D*D)=252E
转成10进制：P3=9518
