Problem Statement

Write a C program to check whether a triangle can be formed given three side lengths.

Input Format

Three space-separated integers representing side lengths A, B, and C.

Output Format

Print 'Valid' if the triangle is valid, otherwise 'Invalid'.

Constraints

1 <= A, B, C <= 1000

Sample Input

3 4 5

Sample Output

Valid

Explanation

Sum of any two sides is strictly greater than the third side (e.g., 3+4 > 5).

Starter Code

#include <stdio.h>

int main() {
    int a, b, c;
    if (scanf("%d %d %d", &a, &b, &c) == 3) {
        // 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
