please explain with steps what is happening in this code, and what would be the output. thanks.

Example: Pushing Info Down class Node { T data; int depth; Node left, right; } setDepth(Node t, int i) { if(t == null) return; t.depth = i; setDepth(t.left, t.depth+1); setDepth(t.right, t.depth+1); } setDepth(root, 0) Example: Pushing Info Up 671 class Node { T data; int height; Node left, right; } 222 551 int setHeight (Node t){ if(t == null) return -1; int h1 = setHeight(t.left), int h2 = setHeight(t.right); hChild = max(h1, h2); t.height = hChild + 1; } setHeight(root)
