Problem Statement

Write a C program to compute the result of shifting an integer N left by K bits (N << K).

Input Format

Two space-separated integers N and K.

Output Format

Print the integer result of N << K.

Constraints

0 <= N <= 10000, 0 <= K <= 15

Sample Input

20

Explanation

5 left shifted by 2 bits (5 * 2^2) equals 20.

Starter Code

#include <stdio.h>

int main() {
    int n, k;
    if (scanf("%d %d", &n, &k) == 2) {
        // Write your code here
    }
    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
