Day29 Bitwise AND

Objective

Welcome to the last day! Today, we’re discussing bitwise operations. Check out the Tutorial tab for learning materials and an instructional video!


Day28 RegEx, Patterns, and Intro to Databases

Objective

Today, we’re working with regular expressions. Check out the Tutorial tab for learning materials and an instructional video!


Day26 Nested Logic

Objective

Today’s challenge puts your understanding of nested conditional statements to the test. You already have the knowledge to complete this challenge, but check out the Tutorial tab for a video on testing!


Day25 Running Time and Complexity

Objective

Today we’re learning about running time! Check out the Tutorial tab for learning materials and an instructional video!


Day24 More Linked Lists

Objective

Check out the Tutorial tab for learning materials and an instructional video!


Task

A Node class is provided for you in the editor. A Node object has an integer data field, data, and a Node instance pointer, next, pointing to another node (i.e.: the next node in a list).

A removeDuplicates function is declared in your editor, which takes a pointer to the head node of a linked list as a parameter. Complete removeDuplicates so that it deletes any duplicate nodes from the list and returns the head of the updated list.

Note: The head pointer may be null, indicating that the list is empty. Be sure to reset your next pointer when performing deletions to avoid breaking the list.

Day23 BST Level-Order Traversal

Objective

Today, we’re going further with Binary Search Trees. Check out the Tutorial tab for learning materials and an instructional video!


Task

A level-order traversal, also known as a breadth-first search, visits each level of a tree’s nodes from left to right, top to bottom. You are given a pointer, root, pointing to the root of a binary search tree. Complete the levelOrder function provided in your editor so that it prints the level-order traversal of the binary search tree.

Hint: You’ll find a queue helpful in completing this challenge.

Day22 Binary Search Trees

Objective

Today, we’re working with Binary Search Trees (BSTs). Check out the Tutorial tab for learning materials and an instructional video!


Task

The height of a binary search tree is the number of edges between the tree’s root and its furthest leaf. You are given a pointer, root, pointing to the root of a binary search tree. Complete the getHeight function provided in your editor so that it returns the height of the binary search tree.

Day21 Generics

Objective

Today we’re discussing Generics; be aware that not all languages support this construct, so fewer languages are enabled for this challenge. Check out the Tutorial tab for learning materials and an instructional video!


Day20 Sorting

Objective

Today, we’re discussing a simple sorting algorithm called Bubble Sort. Check out the Tutorial tab for learning materials and an instructional video!


Day19 Interfaces

Objective

Today, we’re learning about Interfaces. Check out the Tutorial tab for learning materials and an instructional video!
