Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.Scanner;
public class Exercise25 {
public static void main(String args[])
{
Scanner in = new Scanner(System.in);
System.out.print("Input the number: ");
int n = in.nextInt();
int count = 1;
int no_of_spaces = 1;
int start = 0;
for (int i = 1; i < (n * 2); i++)
{
for (int spc = n - no_of_spaces; spc > 0; spc--)
{
System.out.print(" ");
}
if (i < n)
{
start = i; //for number
no_of_spaces++; //for spaces
} else
{
start = n * 2 - i; //for number
no_of_spaces--; //for space
}
for (int j = 0; j < count; j++)
{
System.out.print(start);
if (j < count / 2)
{
start--;
} else
{
start++;
}
}
if (i < n)
{
count = count + 2;
} else {
count = count - 2;
}
System.out.println();
}
}
}
