Write a recursive function that calculates the sum of the branch lengths given a tree and node number. The function should return the sum of all branches leading from the node to all descendant leaves. The function should return 0 if a leaf is given and return an error message if the node/leaf doesn't exist. Jse your function and print the output for nodes: 17, 15, 13, 9, 2
