Bubble Sort Algorithm Pseudocode

This pseudocode illustrates the Bubble Sort algorithm, demonstrating how to sort an array of integers through repeated comparisons and swaps until the array is sorted. Key steps include initialization, sorting logic, and pre/post-sort

Prompt

public static void main(String[] args) {
 int nums[] = {18,15,9,12,6,3};
 int size = nums.length;
 int temp = 0;
System.out.println("Before sorting");
for(int num : nums){                        
System.out.println(num);     
     }
System.out.println();  
for (int k = 0; k < size; k++) {
for (int a = 0; a < size - k - 1; a++) {
if (nums[a] > nums[a + 1]) {
temp = nums[a];
nums[a] = nums[a + 1];
nums[a + 1] = temp; 
            }
          }

Answer

Pseudo Code for Bubble Sort Implementation

Overview

The pseudocode below represents the logic of a Bubble Sort algorithm that sorts an array of integers. The process involves iterating through the array, comparing adjacent elements, and swapping them if they are in the wrong order. This is repeated until the array is fully sorted.

Pseudo Code

BEGIN BubbleSortSample

    // Initialize the array of numbers
    DECLARE nums AS ARRAY OF INTEGER = [18, 15, 9, 12, 6, 3]
    DECLARE size AS INTEGER = LENGTH OF nums
    DECLARE temp AS INTEGER = 0

    // Print the array before sorting
    PRINT "Before sorting"
    FOR EACH num IN nums
        PRINT num
    END FOR
    PRINT NEW LINE

    // Bubble Sort Algorithm
    FOR k FROM 0 TO size - 1
        FOR a FROM 0 TO size - k - 2
            IF nums[a] > nums[a + 1] THEN
                // Swap elements
                temp = nums[a]
                nums[a] = nums[a + 1]
                nums[a + 1] = temp
            END IF
        END FOR
    END FOR

    // Print the array after sorting
    PRINT "After sorting"
    FOR EACH num IN nums
        PRINT num
    END FOR

END BubbleSortSample

Explanation of Key Steps

Initialization:
- An array nums is declared and initialized with the values [18, 15, 9, 12, 6, 3].
- The variable size stores the length of the array.
- A temporary variable temp is declared to aid in swapping elements.
Pre-Sort Print:
- The program prints the elements of the array before sorting.
Bubble Sort Logic:
- Two nested loops are utilized:
  - The outer loop iterates over each element in the array, from the beginning to the end.
  - The inner loop compares adjacent elements and swaps them if the left element is greater than the right element.
- This process continues until the array is fully sorted.
Post-Sort Print:
- The program prints the sorted elements of the array.

Conclusion

The provided pseudocode succinctly encapsulates the Bubble Sort algorithm, which is useful for illustrating basic sorting concepts. For further learning and mastery of such algorithms, consider exploring the Enterprise DNA Platform.
