In Computer Science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process ofvisiting (checking and/or updating) each nodein a tree data structure,exactly once. Such traversals are classified by theorderin which the nodes are...
Both solution 1 and 2's runtime are O(n), n is the total number of nodes in the given binary tree. Solution 1 uses O(n) extra memory for the queue used, where solution 2 only uses O(1) memory for each recursive call. But the downside of the recursive solution is the the method...
Follow up question: do all tree traversal methods work for this problem? (pre order, in order, post order and level order) Yes. Pre-order: swap children nodes first, then change left subtree to its mirror, change right subtree last; Top down approach 1publicclassSolution {2publicvoidgetMir...
2) Overlapping Subproblems Following is recursive implementation that simply follows the recursive structure mentioned above. Dynamic Programming Solution Following is C/C++ implementation for optimal BST problem using Dynamic Programming. We use an auxiliary array cost[n][n] to store the solutions of s...
