As part of HackerAd's advertising system analytics, a team needs a list of customers whe have a maximum number of failure events $($status $=$ "failure"$)$ in their campaigns. For all customers with more than $3$ events with status $=$ 'failure', report the customer name

and their number of failures.

The result should be in the following format: customer, failures.

$$ customer is a candidate's full name, the first$\_$name and last$\_$name separated by a single space.

$$ The order of the output is not important.
