Linear Search in a 3D Array with Java

Linear Search, a versatile algorithm for element retrieval, becomes a fascinating exploration when applied to three-dimensional (3D) arrays. In this guide, we’ll dive into the intricacies of implementing Linear Search in a 3D array using Java, unravelling the complexities of navigating through multi-dimensional data structures.

Understanding 3D Array Linear Search:

Searching for a specific element in a 3D array involves traversing not only rows and columns but also the depth of the array. Systematically check each element in a 3D array until you find the desired target or explore the entire array. This algorithmic approach sets the groundwork for efficient searching in multidimensional datasets.

Linear Search in a 3D Array Program:

Program – Linear Search in 3D Array
public class LinearSearch3D {
    // Method: Perform Linear Search in a 3D array
    public static int[] linearSearch3D(int[][][] array, int target) {
        // Loop through layers
        for (int i = 0; i < array.length; i++) { 
            // Loop through rows in each layer
            for (int j = 0; j < array[i].length; j++) { 
                // Loop through columns in each row
                for (int k = 0; k < array[i][j].length; k++) {
                    if (array[i][j][k] == target) {
                       // Return indices when finding the target element
                        return new int[]{i, j, k}; 
                    }
                }
            }
        }
        // Return {-1, -1, -1} if the target element is not found in the 3D array
        return new int[]{-1, -1, -1}; 
    }

    // Main method: Test Linear Search in 3D array
    public static void main(String[] args) {
        // Example 3D array
        int[][][] array3D = {
            {{1, 2, 3}, {4, 5, 6}},
            {{7, 8, 9}, {10, 11, 12}}
        };
        int targetElement = 11; // Target element for demonstration

        // Perform Linear Search and store the result in the 'result' array
        int[] result = linearSearch3D(array3D, targetElement);
        
        // Targeted element
         System.out.println("Element to find: "+targetElement);
        // Check if the target element was found and print the result accordingly
        if (result[0] != -1) {
            System.out.println("Found element " + targetElement + " at position: (" + result[0] + ", " + result[1] + ", " + result[2] + ")");
        } else {
            System.out.println("Element " + targetElement + " not found in the 3D array");
        }
    }
}

Breaking Down the Implementation:

Let’s break down the Java program that implements Linear Search in a 3D array:

Method linearSearch3D:

  • This method performs Linear Search in a 3D array.
  • It takes a 3D array (array) and a target element (target) as parameters.
  • The method uses nested loops to traverse through layers (i), rows (j), and columns (k) of the 3D array.
  • If the target element is found, it returns an array containing the indices (new int[]{i, j, k}).
  • If the algorithm doesn’t find the target element, it returns {-1, -1, -1}.

Main Method:

  • In the main method, an example 3D array (array3D) is declared and initialized.
  • The target element (targetElement) is set to 11 for demonstration purposes.
  • The linearSearch3D method is called with the 3D array and the target element, and the result is stored in the result array.
  • The program then checks if the first index of the result is not -1. If the condition is true, the program prints the position where it found the element. If false, it prints a message indicating the element’s absence in the 3D array.

Output:

Output – Linear Search in 3D Array
Element to find: 11
Found element 11 at position: (1, 1, 1)

Conclusion:

Implementing Linear Search in a 3D array opens up new dimensions of understanding array manipulation in Java. This foundational knowledge lays the groundwork for more complex algorithms and efficient data retrieval in multidimensional scenarios. Happy coding!
