Binary tree is full if all of its vertices have either zero or two children. Let Bn denote number of full binary trees with n vertices. Illustrate by induction (substitution) that Bn is 2 (n) .
Using the recursive algorithm, described in the previous section, develop an iterative function with the same functionality as the recursive nextPermutation function. Recall, that the iterative function should not contain recursive calls - it uses..
