[algogeeks] merging 2 search trees
You are given two height balanced binary search trees T and T’, storing m and n elements respectively. Every element of tree T is smaller than every element of tree T’. Every node u also stores height of the subtree rooted at it. Using this extra information how can you merge the two trees in time O(log m + log n) (preserving both the height balance and the order)? -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] merging 2 search trees
Find the node in T which is the maximum(which is either the root or the rightmost in the right subtree). After finding this node, just make the right child of this node point to the root of T'.

@ above height will not be balanced then On 21 January 2011 19:15, nishaanth nishaant...@gmail.com wrote: Find the node in T which is the maximum(which is either the root or the rightmost in the right subtree).
