Check this but will not tell the nodes only the length of the path...

```
int maxDepth(Node root) {
if(root == null) {
return 0;
} else {
int ldepth = maxDepth(root.left);
int rdepth = maxDepth(root.right);
return ldepth>rdepth ? ldepth+1 : rdepth+1;
}
}
int longestPath(Node root)
{
if (root == null)
return 0;
int ldepth = maxDepth(root.left);
int rdepth = maxDepth(root.right);
int lLongPath = longestPath(root.left);
int rLongPath = longestPath(root.right);
return max(ldepth + rdepth + 1, max(lLongPath, rLongPath));
}
```
