Find the maximum 3-digit number from an array of both negative and positive numbers.

• Iterate through the array and keep track of the 3 largest positive numbers.

• Iterate through the array and keep track of the 3 smallest negative numbers.

• Compare the largest positive numbers with the smallest negative numbers to find the maximum 3-digit number.

The 3 hat problem involves guessing the color of your own hat based on the colors of hats worn by others.

• Each person can see the colors of the hats of the people in front of them, but not their own hat color.

• By analyzing the guesses and hat colors of others, one can deduce their own hat color.

• Communication and logical reasoning are key to solving this puzzle.

A recursive program is a function that calls itself within its own code.

• Recursion is a technique where a function calls itself to solve smaller instances of the same problem.

• It involves breaking down a problem into smaller subproblems until a base case is reached.

• Examples of recursive programs include factorial calculation, Fibonacci sequence generation, and tree traversal algorithms.

Iterative tree traversal using a stack instead of recursion

• Use a stack to keep track of nodes to visit

• Start with the root node and push it onto the stack

• While the stack is not empty, pop a node, visit it, and push its children onto the stack

AVL and BST trees are types of binary search trees, with AVL trees being self-balancing.

• BST (Binary Search Tree) is a type of binary tree where each node has at most two children, with left child < parent < right child.

• AVL (Adelson-Velsky and Landis) tree is a self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one.

• AVL trees maintain O(log n) time complexity for insertion, deletion, and search operations due to their sel...read more

Debugging a bug process involves identifying, isolating, and fixing issues in software code.

• Identify the bug by reproducing the issue and analyzing error messages.

• Isolate the bug by narrowing down the code where the issue occurs.

• Fix the bug by making necessary code changes and testing the solution.

• Verify the fix by retesting the software to ensure the bug is resolved.
