Problem - Download Speed

CSES problem: you have a computer network with $n$ nodes and $m$ connections. Each connection has a maximum data rate. Find the maximum download speed from computer $1$ to computer $n$. This is a direct application of max flow.

Computer $1$ is the source, computer $n$ is the sink, and each connection is an edge with capacity equal to its data rate. Run Edmonds-Karp and output the maximum flow value. That is the answer.
