I am trying to visualize post-order traversal on a tree.
What I want is to wait for the user to press a key, lets say the ‘up-arrow-key’ before continuing to the next step in the eachAfter iteration. Is there a way to do this?
root.copy().eachAfter((currentNode) => {
//Code that colors the current node here.
// Wait until the user press up arrow key before moving to the next iteration.
})
