Maximum Edges to Connect Employees to Special Employees

Problem Preview

"### Problem There are $n$ employees in a company, out of which there are $k$ special employees who have data network and share their mobile hotspots with other employees. There are employee edges connections already made between the employees, where the / connection connects the employees $from[i]$ and $to[i]$, such that either of the employees, $from[i]$ and $to[i]$ can share a mobile hotspot. Two employees $x$ and $y$ are connected if there is a path between them. All the employees connected to a special employee $x$ will use the mobile hotspot of the special employee $x$. Up to now, to restrict data usage, any employee was connected to at most one special employee. As data consumption has increased, any employee can be connected to at most $m$ number of special employees. Find the maximum number of edges that can be added to the graph such that any employee is connected to at most $m$ special employees."
