ITCS214 - Data Structures and Algorithms Lab

Introduction

This repository contains my Java implementations of fundamental data structures and algorithms class at De La Salle University Dasmarinas.

Overview

The lab activity/repository covers the following core topics:

• Arrays: Basic data structure for storing elements.

• Lists: Linear data structures that allow elements to be inserted or removed at any position.

• Linked Lists: Linear data structure where elements are not stored in contiguous memory locations.

• Stacks: LIFO (Last-In-First-Out) data structure.

• Queues: FIFO (First-In-First-Out) data structure.

• Graphs: Non-linear data structures consisting of nodes and edges.

• Trees/Binary Trees: Hierarchical data structures with a root node and child nodes.

Note:

Specific implementations and problem-solving techniques will be provided during the lab sessions. The midterm and final exams will assess your understanding of the concepts and your ability to apply them to solve problems.

Cloning the Repository

git clone https://github.com/keonbe/ITCS214.git
cd your-repo

Open the project in IntelliJ IDEA and ensure your Java SDK is set up under File > Project Structure > Project.

Troubleshooting

Issue: IntelliJ shows Decompiled .class file, bytecode version: 61.0 (Java 17) instead of source code.

Solution:

1. In Project Explorer, check if your .java source files exist under src/.
2. If missing, right-click the root directory → "Mark Directory as" → "Sources Root".
3. Restart IntelliJ IDEA and rebuild the project (Build > Rebuild Project).

Now, IntelliJ should recognize and compile your Java files correctly.

Contributing Feel free to contribute to this repository by:

• Adding new data structures and algorithms.
• Improving existing implementations.
• Fixing bugs.
