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
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...
For the above tree the output should be 5, 10, 3, 14, 25. If there are multiple bottom-most nodes for a horizontal distance from root, then print the later one in level traversal. For example, in the below diagram, 3 and 4 are both the bottom-most nodes at horizontal distance 0, ...
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...
