10093번: 숫자

 

문제를 제대로 읽고 맞는 자료형을 써야하는 문제였다. ( int -> long )

 

public class Q10093 {
	static Scanner sc;
	static long left;
	static long right;
	
	public static void main(String args[]) {
		solve();
	}
	
	public static void solve() {
		init();
		answer();
	}
	
	public static void init() {
		sc = new Scanner(System.in);
		left = sc.nextLong();
		right = sc.nextLong();
		if(left > right) {
			long temp = right;
			right = left;
			left = temp;
		}
	}
	
	public static void answer() {
		if(right == left) {
			System.out.println(0);
			return;
		}
		
		long twoNumberInCount = right - left - 1;
		System.out.println(twoNumberInCount);
		
		for(long num = left + 1; num < right; num++) {
			System.out.print(num + " ");
		}
	}
