Answer 1

public void PrintAllPossiblePath(Node node,List nodelist)
{
    if(node != null)
    {
            nodelist.add(node);
            if(node.left != null)
            {
                PrintAllPossiblePath(node.left,nodelist);
            }
            if(node.right != null)
            {
                PrintAllPossiblePath(node.right,nodelist);
            }
            else if(node.left == null && node.right == null)
            {

            for(int i=0;i

nodelist.remove(node) is the key, it removes the element once it prints the respective path
