    Top 12 DSA Projects with Source Code

    Here are some of the best projects for data structures and algorithms that may be used to practice programming and gain practical expertise. These projects offer an engaging journey of learning and problem-solving, covering a wide range of subjects, from basic data structures to cutting-edge algorithms.

    1. Cash Flow Minimizer (Graphs, Heaps, and Multisets)

    Cash Flow Minimizer - DSA projects
    GitHub

    The Cash Flow Minimizer projects based on data structures and algorithms to the problem of cash flow optimization by using graphs, heaps, and multisets. The project's objective is to determine the smallest number of transactions necessary to settle the debts between a group of people.

    The project employs a graph data format to represent both the vertices—persons themselves—and the edges—debts between individuals. The program then uses the idea of heaps to determine which people have the highest and lowest debt loads. The procedure then generates transactions between these two parties, updates the debts, and continues until all debts are paid.

    To keep track of transactions and their sums, the project also uses multisets, a data structure that enables storing numerous instances of the same information. The multisets assist in determining the least number of transactions necessary to pay off the debts.

    The Cash Flow Minimizer project serves as an example of the power and adaptability of DSA in dealing with practical issues. The project is especially helpful in situations where it is difficult to determine the minimum number of transactions necessary to settle the debts between a group of people.

    2. Map Navigator (Dijkstra’s Algorithm)

    The Map Navigator project, based on data structures and algorithms, is an advanced mapping application that utilizes an improved version of Dijkstra's algorithm to determine the shortest route between two points on a map. By employing cutting-edge technology and innovative approaches, the Map Navigator ensures fast and accurate navigation results for users.

    In this project, the map is initially visualized as a graph, with each place acting as a node and the distance between them as an edge. The graph is then subjected to Dijkstra's algorithm to determine the shortest route between the two points.

    As it moves along the graph, the algorithm continuously updates the distances it has tentatively assigned to each site on the map. The computer then chooses the site with the shortest tentative distance and examines the areas around it, adjusting the tentative distances of those areas as necessary. This step is repeated by the algorithm until it reaches the desired place, and the shortest path is found.

    3. Sudoku Solver (Backtracking)

    Sudoku solver mini projects on data structures and algorithms use the backtracking algorithm to resolve Sudoku puzzles. Sudoku is a logic-based number puzzle game that requires you to fill in a 9x9 grid with numbers from 1 to 9, with no repetitions allowed in the rows, columns, or 3x3 subgrids.

    The first step in the Sudoku Solver project is to draw the puzzle as a 9x9 grid and fill it in with the specified numbers. The puzzle is then solved using the backtracking approach by iteratively trying out various values in each cell until a solution is discovered.

    When the backtracking algorithm runs into a dead end, that is, when it comes into a contradiction that renders the problem impossible to solve, it will turn around and try another possible solution for each cell in the grid. Once a viable answer is found, the algorithm goes back and tests different values in the earlier cells.

    The Sudoku Solver data structures and algorithms projects in Python show how the backtracking algorithm can be used in real-world situations to solve challenging puzzles like Sudoku. It is beneficial for puzzle fans, game creators, and anybody else interested in logic-based problem-solving.

    4. Snakes Game (Arrays)

    The project "Snake's Game" is an excellent example of a project for data structures and algorithms. It utilizes arrays to implement the well-known Snake game, where a user-controlled snake moves around a grid, consuming food to grow while avoiding collisions with walls and its own body. This project not only offers an enjoyable gaming experience but also demonstrates the application of data structures and algorithms in game development.

    The grid is first represented as a 2D array in the Snakes Game project, along with the snake's beginning position and direction. The user can then use the arrow keys to direct the snake during the game's looping portion. In the following loop iterations, the snake's movement is updated, and arrays are used to check for collisions with the walls and the snake's body.

    The arrays are used to maintain track of the locations of the food and the placements of the snake's body parts. The snake expands by one segment as it consumes the meal, updating the array of its body segments. The game ends when the snake slams into the walls or its own body.

    The Snakes Game project shows how arrays can be used in real-world settings to design a well-known game. It is helpful for those who want to learn how to use arrays in game creation as well as for game creators themselves.

    5. File Zipper (Greedy Huffman Encoder)

    File Zipper
    GitHub

    The File Zipper project, specifically developed for data structures and algorithms projects in C++ source code, utilizes the well-known lossless data compression algorithm Greedy Huffman Encoder technique. This project aims to compress files by minimizing their size. 

    The Greedy Huffman Encoder technique works by allocating shorter codes to characters that are used more frequently in a file and longer codes to characters that are used less frequently. By implementing this algorithm in C++, the project showcases how data structures and algorithms can be utilized to optimize file compression and achieve efficient storage.

    The first step in the File Zipper project is to read data from a file and make a frequency table of the appearances of each character. The Huffman tree is created using the frequency table, and each leaf node represents a character. The code for each leaf node is obtained from the path from the root to the leaf node.

    The data is then encoded using the Huffman tree by swapping out each character with its appropriate code, creating a compressed file. The decoded data is then written to a new file along with the necessary data from the Huffman tree.

    6. Graphical Calculator

    Graphical Calculator
    GitHub

    The Graphical Calculator project makes use of a variety of data structures and algorithms to construct a calculator that can handle mathematical expressions and display the results in a graphical user interface (GUI). 

    The Shunting Yard Algorithm is used to first parse the user's mathematical expression in the Graphical Calculator project. The approach changes the expression's notation from infix to postfix, which can be quickly evaluated using a stack data structure.

    The postfix expression is then evaluated by the project using a binary expression tree. The postfix expression is parsed to create a tree where each operator is a node, and its operands are its children. This creates the binary expression tree. The expression is then evaluated by moving up the tree starting at the root node.

    The user-entered mathematical expression and the outcome of the expression assessment are displayed in the Graphical User Interface (GUI) of the Graphical Calculator project. Additionally, it has a number of buttons for addition, subtraction, multiplication, and division in mathematics.

Through a text-based interface, the Terminal Shell project enables users to carry out numerous commands, explore the file system, and carry out other tasks.

    Implementing a command parser that can recognize and carry out user-inputted commands is the first step in the Terminal Shell project. To quickly find and carry out commands, the command parser employs a variety of data structures and methods, including hash tables and binary trees.

    A file system navigator is also implemented in the project, enabling users to move around the file system and carry out operations on files like creating, reading, writing, and deleting files and directories. The file system navigator effectively searches and navigates the file system using a variety of data structures and techniques, including linked lists and trees.

    The Terminal Shell project also has features that improve the user experience and boost productivity, like command history, command autocompletion, and input/output redirection.
