The way these 1's and 0's flip are like the Lights Out game, except I only have to worry about a single row.
So, if I have 1001 and I "press" the first bit it will become 0101 Now if I "press" the third bit, it will become 0010 and so on until you get the string to be all zeros.

Instead of storing elements it only organizes elements. This allows programmers to insert elements into the QuadTree and maintain access of those elements outside the QuadTree.
