Lecture Data Structures: Lesson 36 provide students with knowledge about union by size; maintain sizes (number of nodes) of all trees, and during union; make smaller tree the subtree of the larger one; implementation: for each root node i, instead of setting parent[i] to -1, set it to -k if tree rooted at i has k nodes;...

Lecture Data Structures: Lesson 27 provide students with knowledge about properties of binary tree; threaded binary tree; the overhead of stack operations during recursive calls can be costly; the same would true if we use a non-recursive but stack-driven traversal procedure;...

Lecture Data Structures: Lesson 30 provide students with knowledge about inserting into a Heap; finding the minimum is easy; it is at the top of the heap; deleting it (or removing it) causes a hole which needs to be filled;...
