Problem Statement

Write a C program to sort the elements of a queue in ascending order using an auxiliary stack or array.

Input Format

First line contains n. Second line contains n elements.

Output Format

Print the sorted queue elements from front to rear separated by spaces.

Constraints

1 <= n <= 50

Sample Input

5
40 10 50 30 20

Sample Output

10 20 30 40 50

Explanation

Dequeue elements into an array, sort the array using standard sorting logic, and re-enqueue them.

Starter Code

#include <stdio.h>
#include <stdlib.h>

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Write your code here to sort queue elements
    }
    return 0;
}

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
