https://www.geeksforgeeks.org/generic-tree-level-order-traversal/ this link is one of the only code examples I could find anyway this seems quite ugly especially when adding a new node 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ...
2. From bottom to top, for each node A, treat it as a root node and count the total number of nodes in this subtree recursively. 3. For each node A, check if there exists an edge that halves the given input tree in this subtree of root A. If any of the 3 is true, then ther...
Two trees are isomorphic in the following 2 cases. 1. both trees are null; 2. a.neither tree is null; b.their roots' values are the same; c. either tree 1's left subtree is isomorphic with tree 2's left subtree and tree 1's right subtree is isomorphic with tree 2's right subtr...
It’s a tradition that some say predates celebrating Christmas. Bringing a real miniature pine tree in to your home at this time of year and putting all kinds of shiny decorations on it, is something that happens in millions of homes around the world. If you don’t already have a Christm...

One of the more unusual “trees” in our collection, the Tannenboing is made out of recycled aluminum. It’s flexible enough to be able to hang from the ceiling or stand on the floor. For next season, just pack it up or recycle it. ...

In this case, the uncle is black, so we have case 2 ... Move x up and rotate left. Still not a red-black tree .. the uncle is black, but x's parent is to the left .. Change the colours of 7 and 11 and rotate right .. ...
