C++ Exercises: Check three given integers and return true if the difference between small and medium and the difference between medium and large is same

C++ Basic Algorithm: Exercise-56 with Solution

Equal Differences for Three Integers

Write a C++ program to check three given integers (small, medium and large) and return true if the difference between small and medium and the difference between medium and large is same.

Sample Solution:

C++ Code :

#include <iostream>

using namespace std;

// Function 'test' checks if the differences between the numbers are equal
bool test(int x, int y, int z)
{
    // Checks for the condition when x is the largest number
    if (x > y && x > z && y > z)
        return x - y == y - z; // Returns true if differences are equal

    // Checks for the condition when x is the largest number, but z is the smallest
    if (x > y && x > z && z > y)
        return x - z == z - y; // Returns true if differences are equal

    // Checks for the condition when y is the largest number
    if (y > x && y > z && x > z)
        return y - x == x - z; // Returns true if differences are equal

    // Checks for the condition when y is the largest number, but z is the smallest
    if (y > x && y > z && z > x)
        return y - z == z - x; // Returns true if differences are equal

    // Checks for the condition when z is the largest number
    if (z > x && z > y && x > y)
        return z - x == x - y; // Returns true if differences are equal

    // Returns true if differences are equal (when z is the largest number and y is the smallest)
    return z - y == y - x;
}

int main() 
{
    // Testing the 'test' function with different sets of numbers
    cout << test(4, 5, 6) << endl;  
    cout << test(7, 12, 13) << endl; 
    cout << test(-1, 0, 1) << endl;
    return 0;    
}

Sample Output:

1
0
1

Previous: Write a C++ program to check two given integers and return the value whichever value is nearest to 13 without going over. Return 0 if both numbers go over.
Next: Write a C++ program to create a new string using two given strings s1, s2, the format of the new string will be s1s2s2s1.
