1. Triple Sum Condition

Write a C program to compute the sum of the two input values. If the two values are the same, then return triple their sum.

C Code:

#include <stdio.h> // Include standard input/output library

int test(int x, int y); // Declare the function 'test' with two integer parameters

int main(void)
{
    // Call the function 'test' with arguments 1 and 2 and print the result
    printf("%d", test(1, 2));

    // Print a newline for formatting
    printf("\n");

    // Call the function 'test' with arguments 2 and 2 and print the result
    printf("%d", test(2, 2));
}
// Function definition for 'test'
int test(int x, int y)
{
    // Conditional expression: If x is equal to y, return (x + y) multiplied by 3, otherwise return x + y
    return x == y ? (x + y) * 3 : x + y;
}

Sample Output:

3
12

Explanation:

int test(int x, int y) {
  return x == y ? (x + y) * 3 : x + y;
}

The above function takes in two integer parameters, x and y. It uses the ternary operator to check if x is equal to y. If x is equal to y, it returns the result of (x + y)*3. Otherwise, it returns the result of x + y.

Time complexity and space complexity:

Time complexity: The time complexity of the function is O(1) as the function involves a single conditional operation and two arithmetic operations that take constant time.

Space complexity: The space complexity of the function is O(1) as the function only uses a fixed amount of space to store the variables and the return value.
