Study Notes
- In a binary search tree, each node in the left subtree has a value less than the node's value.
- Searching for a node in a balanced BST has a time complexity of O(log n).
- When inserting a new node into a BST, it is always inserted as a leaf node.
- A well-implemented Hash Table has an average-case time complexity for search of O(1).
- Binary search trees are not typically used as priority queues.
- Dynamic programming relies on the principle of overlapping subproblems.
- Dynamic programming can efficiently solve finding the shortest path in a graph, the knapsack problem, and Fibonacci sequences.
- Dynamic programming typically reduces time complexity but increases space complexity compared to recursion.
- Storing results of expensive function calls for later use is called memoization.
- The steps in dynamic programming are identifying the base cases, defining the recursive relation, and optimizing by storing results.
- The worst-case time complexity of searching in a Binary Search Tree (BST) is O(N).
- Inorder traversal of a BST gives elements in sorted order.
- Calculating Fibonacci numbers using recursion with memoization has a time complexity of O(N).
- The 0/1 Knapsack problem is best solved using Dynamic Programming.
