Problem Statement

Write a C program to simulate a Circular Deque supporting insert and delete operations at both ends.

Input Format

Capacity and sequence of operations (1 val for insertFront, 2 val for insertRear, 3 for deleteFront, 4 for deleteRear).

Output Format

Print elements from front to rear separated by spaces.

Constraints

1 <= capacity <= 50, 1 <= ops <= 100

Sample Input

5 4
2 10
2 20
1 5
4

Sample Output

5 10

Explanation

Manage circular buffer pointers for front and rear insertions and deletions.

Starter Code

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

int main() {
    int cap, ops;
    if (scanf("%d %d", &cap, &ops) == 2) {
        // Write your code here for circular deque simulation
    }
    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
