Create a string from two given strings by concatenating common characters of the given strings. Sample Input harry, hermione dean, tom Sample Output hrrhr Nothing in common. Again, you have lost your USIS password!! You went to the registrar office and requested for a new password. This time, you need to follow some rules to set your password. Otherwise, they won't change it. The rules are At least one lowercase letter At least one uppercase letter At least one digit (0-9) At least one special character (_ , $ , #, @) Your task is to find whether a given password follows all those rules. If it breaks any rule, you have to print Lowercase Missing, Uppercase Missing, Digit Missing or Special Missing respective to the missing case. For more than one rule break, print all the rules that were broken (order doesn't matter). If the password is ok, print OK.
