Add Three Numbers

Accept three integers and print their sum.

Understand the Problem

Problem Statement

Accept three numbers and print their sum.

Constraints

The input consists of exactly three integers separated by spaces
Each integer can be within the standard 32-bit signed integer range (-2,147,483,648 to 2,147,483,647)
The output should be a single integer representing the sum

Examples

Example 1

Input

5 2 4

Output

Explanation

5 + 2 + 4 = 11. The three numbers are read from input, added together, and the sum 11 is printed.

Example 2

Input

25 15 10

Output

Explanation

25 + 15 + 10 = 50. The three numbers are read from input, added together, and the sum 50 is printed.

Solution

#include <stdio.h>

int main() {
    int num1, num2, num3;
    scanf("%d %d %d", &num1, &num2, &num3);
    printf("%d", num1 + num2 + num3);
    return 0;
}

Time:O(1) - Constant time operations (reading 3 integers and 1 addition)

Space:O(1) - Only uses 3 integer variables regardless of input size

Approach:

Explanation:

#include <stdio.h> - Includes standard input/output library for scanf and printf
int main() - Main function entry point
int num1, num2, num3; - Declares three integer variables to store input
scanf("%d %d %d", &num1, &num2, &num3); - Reads three integers from standard input
printf("%d", num1 + num2 + num3); - Calculates and prints the sum
return 0; - Returns 0 to indicate successful execution
