needs to do a form verification, the requirements are as follows:
password must be between 6 and 10 digits, and the first character is required to be an uppercase letter, and the password needs at least one-sharp symbol
to come up with the answer after thinking about it for a long time.
^ Amurz [0-9a-zA-Z] {5pm 9}
this is close to success, but the problem is also obvious
^ Amurz {5pm 9}
this does not contain at least one condition, so it is OK not to write-sharp.
ask the master for advice, thank you!
