Algorithm Analysis

The input number can be negative. A number $n$ is single-digit if $- 9 \leq n \leq 9$ .

Algorithm Implementation

Read the input number $n$ .

scanf("%d", &n);

Print the response.

if (n > -10 && n < 10) puts("Ok");
else puts("No");

Java Implementation

import java.util.*;

public class Main
{
    public static void main(String[] args)
    {
        Scanner con = new Scanner(System.in);
        int n = con.nextInt();
        if (n > -10 && n < 10) System.out.println("Ok");
        else System.out.println("No");
        con.close();
    }
}

Python Implementation

n = int(input())
if n > -10 and n < 10: print("Ok")
else: print("No")
