Sorting Strings using Bubble Sort

Last Updated : 14 Mar, 2023

Given an array of strings arr[]. Sort given strings using Bubble Sort and display the sorted array.

In Bubble Sort, the two successive strings arr[i] and arr[i+1] are exchanged whenever arr[i]> arr[i+1]. The larger values sink to the bottom and are hence called sinking sort. At the end of each pass, smaller values gradually “bubble” their way upward to the top and hence called bubble sort.

After all the passes, we get all the strings in sorted order.

Let us look at the code snippet

C++

   // C++ implementation
 
#include <bits/stdc++.h>
using namespace std;
#define MAX 100
 
void sortStrings(char arr[][MAX], int n)
{
    char temp[MAX];
 
    // Sorting strings using bubble sort
    for (int i = 0; i < n - 1; i++) {
        for (int j = 0; j < n - 1 - i; j++) {
            if (strcmp(arr[j], arr[j + 1]) > 0) {
                strcpy(temp, arr[j]);
                strcpy(arr[j], arr[j + 1]);
                strcpy(arr[j + 1], temp);
            }
        }
    }
}
 
int main()
{
    char arr[][MAX] = { "GeeksforGeeks", "Quiz", "Practice",
                        "Gblogs", "Coding" };
    int n = sizeof(arr) / sizeof(arr[0]);
 
    sortStrings(arr, n);
 
    printf("Strings in sorted order are : ");
    for (int i = 0; i < n; i++)
        printf("\n String %d is %s", i + 1, arr[i]);
    return 0;
}
 
  

Java

   // Java implementation
class GFG {
 
    static int MAX = 100;
 
    public static void sortStrings(String[] arr, int n)
    {
        String temp;
 
        // Sorting strings using bubble sort
        for (int j = 0; j < n - 1; j++) {
            for (int i = j + 1; i < n; i++) {
                if (arr[j].compareTo(arr[i]) > 0) {
                    temp = arr[j];
                    arr[j] = arr[i];
                    arr[i] = temp;
                }
            }
        }
    }
 
    // Driver code
    public static void main(String[] args)
    {
        String[] arr = { "GeeksforGeeks", "Quiz",
                         "Practice", "Gblogs", "Coding" };
        int n = arr.length;
        sortStrings(arr, n);
        System.out.println(
            "Strings in sorted order are : ");
        for (int i = 0; i < n; i++)
            System.out.println("String " + (i + 1) + " is "
                               + arr[i]);
    }
}

Output

Strings in sorted order are :   String 1 is Coding  String 2 is Gblogs  String 3 is GeeksforGeeks  String 4 is Practice  String 5 is Quiz

Time Complexity: O(n²)
Auxiliary Space: O(MAX) or O(100)
