Hi @DestinationFAANG
I noticed the following function 'removeLeaves()' is missing for the following problem: 366 Find Leaves of Binary Tree.java

I do not have access to commit and generate PR. It will be great if you could add this method!

private TreeNode removeLeaves(TreeNode node, List<Integer> leaves) {
    if (node == null) {
        return null;
    }

    if (node.left == null && node.right == null) {
        leaves.add(node);
        return null;
    }

    node.left = removeLeaves(node.left, leaves);
    node.right = removeLeaves(node.right, leaves);

    return node;
}
