Same Rightmost Digit for Non-Negative Integers

Write a C++ program to check if two or more integers that are not negative have the same rightmost digit.

Sample Solution:

C++ Code :

#include <iostream>

using namespace std;

// Function 'test' takes three integers (x, y, z) as parameters
bool test(int x, int y, int z)
{
    // Returns true if any two numbers among x, y, and z have the same last digit
    return x % 10 == y % 10 || x % 10 == z % 10 || y % 10 == z % 10;
}

int main() 
{
    // Testing the 'test' function with different sets of numbers
    cout << test(11, 21, 31) << endl;  // Output: 1 (True, as two numbers end with the same digit '1')
    cout << test(11, 22, 31) << endl;  // Output: 1 (True, as two numbers end with the same digit '1')
    cout << test(11, 22, 33) << endl;  // Output: 0 (False, as no two numbers end with the same digit)

    return 0;      
}

Sample Output:

1 
1 
0

Previous: Write a C++ program to check if three given numbers are in strict increasing order, such as 4 7 15, or 45, 56, 67, but not 4 ,5, 8 or 6, 6, 8. However,if a fourth parameter is true, equality is allowed, such as 6, 6, 8 or 7, 7, 7.
Next: Write a C++ program to check three given integers and return true if one of them is 20 or more less than one of the others.
