QUESTION : Mr. Robot’s Password (R)

Mr. Robot is making a website, in which there is a tab to create a password. As other websites, there are rules so that the password gets complex and none can predict the password for another. So he gave some rules like:

– At least one numeric digit

– At Least one Small/Lowercase Letter

– At Least one Capital/Uppercase Letter

– Must not have space

– Must not have slash (/)

– At least 6 characters

If someone inputs an invalid password, the code prints: “Invalid password, try again”.

Otherwise, it prints: “password valid”.

Input Format:

A line with a given string as a password

Output Format:

If someone inputs an invalid password, the code prints: “Invalid password, try again”.

Otherwise, it prints: “password valid”, without the quotation marks.

Constraints:

Number of character in the given string <=10^9

Sample input 1:

abjnlL09

Sample output 1:

password valid

Sample input 2:

jjnaskpk

Sample output 2:

Invalid password, try again
