WebThat BST would be one with the lowest total lookup cost, where that cost is calculated using the approach you worked through earlier on. The terminology for a BST with that property - that it has the best lookup speed for those frequencies among all the possible BSTs that you can make - is an optimal BST. WebGiven keys and frequency at which these keys are searched, how would you create binary search tree from these keys such that cost of searching is minimum.htt...
