BigInteger

Theory

Comparing numbers

Report a typo

Alice wrote a method for checking if at least two given BigInteger numbers are equal. But she has made several mistakes and the method works incorrectly.

Try to fix it.

Write a program in Java 17
import java.math.BigInteger;
import java.util.Scanner;

public class Main {

/**
* It returns true if at least two of three given numbers are equal, otherwise - false.
*/
public static boolean atLeastTwoAreEqual(BigInteger num1, BigInteger num2, BigInteger num3) {
return num1 == num2 || num2 == num2 || num1 == num3; // fix this line
}

/* Do not change code below */
public static void main(String[] args) {
final Scanner scanner = new Scanner(System.in);

final String[] parts = scanner.nextLine().split("\\s+");

BigInteger num1 = null;
BigInteger num2 = null;
BigInteger num3 = null;

try {
num1 = new BigInteger(parts[0]);
num2 = new BigInteger(parts[1]);
num3 = new BigInteger(parts[2]);
} catch (Exception e) {
System.out.println("Can't parse a big integer value");
e.printStackTrace();
}

System.out.println(atLeastTwoAreEqual(num1, num2, num3) ? "YES" : "NO");
}
}
