C#: Check whether two or more non-negative given integers have the same rightmost digit

C# Sharp Basic Algorithm: Exercise-50 with Solution

Same Rightmost Digit in Two or More Integers

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

Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Printing the results of the 'test' method with different integer values
            Console.WriteLine(test(11, 21, 31)); // Output: True (since at least two numbers have the same last digit)
            Console.WriteLine(test(11, 22, 31)); // Output: True (since at least two numbers have the same last digit)
            Console.WriteLine(test(11, 22, 33)); // Output: False (since all numbers have different last digits)
            Console.ReadLine(); // Keeping the console window open
        }

        // Method to check if at least two integers have the same last digit
        public static bool test(int x, int y, int z)
        {
            // Returns true if x's last digit equals y's last digit or x's last digit equals z's last digit or y's last digit equals z's last digit
            return x % 10 == y % 10 || x % 10 == z % 10 || y % 10 == z % 10;
        }
    }
}

Sample Output:

True
True
False

Previous: Write a C# Sharp program to check whether 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# Sharp program to check three given integers and return true if one of them is 20 or more less than one of the others.
