Write pseudocode to manage a connection pool. Your pseudocode must include a function to create a pool (providing a database connection string, database username, and password as parameters), a function to request a connection from the pool, a function to release a connection to the pool, and a function to close the connection pool.

// represents a single connection to the database. 
class Connection { 

} 

// represents a connection pool 
class ConnectionPool { 
    // a list of connections that are in the pool. 
    List<Connection> listOfConnections;
}

// a function to create a pool
ConnectionPool createConnectionPool(string db_conn, string db_username, string db_password) { 

}

// a function to request a connection 
// from the pool
Connection getConnectionFromPool(ConnectionPool pool) { 

}

// a function to release a connection to the pool
void releaseConnectionToThePool(ConnectionPool pool, Connection conn) { 

}

// a function to close the connection pool
void closeConnection(ConnectionPool pool) {
