WebI'd like to know if anyone could help me verify a recursive formula for the minimum possible number of nodes a binary search tree would require to be balanced. So far, I know that the recursive solution for the maximum possible number of nodes is M ( d) = 2 M ( d − 1) + 1, where d is the depth of the BBT. I assume that for the minimum number ... Web5 de nov. de 2024 · If the tree isn’t full or balanced, the analysis is difficult. You can say that for a tree with a given number of levels, average search times will be shorter for the nonfull tree than the full tree because fewer searches will proceed to lower levels.
