Create a function `sum` that implements currying. Currying is a transformation of functions that translates a function from being callable as f(x, y, z) into callable as f(x)(y)(z).

Implement Currying

Given a 2D matrix of numbers, return a spiral traversal of the matrix in the clockwise direction.

Spiral Traversal

Given a `Select All` checkbox - toggle the children's checkboxes in such a way that when the `select all` button is clicked, all the boxes are checked. Similarly, when the button is toggled, the checkboxes become unchecked.

Select All Checkboxes

Given a pointer to the root node of a binary tree, return true if the binary tree is height-balanced. A height-balanced binary tree is a Binary tree in which the difference between the left subtree height and the right subtree height is at most 1. Height of a binary tree is the number of edges between the root node to the longest leaf node.
