Question

Write a program to generate a triangle or an inverted choice. triangle based upon User's choice.

Example 1:	Example 2:
Input: Type 1 for a triangle and Type 2 for an inverted triangle Enter your choice 1 Enter a word: BLUEJ	Input: Type 1 for a triangle and Type 2 for an inverted triangle Enter your choice 2 Enter a word: BLUEJ
Sample Output:  B  L  L U U U  E  E  E  E J  J  J  J  J	Sample Output:  B L U E J B L U E B L U  B L  B

Answer 1

import java.util.*;
public class SQ23
{ public static void main(String args[])
{Scanner ob = new Scanner(System.in);
int i, j, n, len;
String s;

System.out.println("****Menu Driven Program****");
System.out.println("Enter your choice");
System.out.println("1. for Triangle / 2. for Inverted Triangle");
n = ob.nextInt();

System.out.println("Enter the word");
s = ob.next();
len = s.length();

switch(n)
{case 1: System.out.println("\n***Pattern1 Triangle***");
         for (i = 0; i < len; i++)
         {for (j = 0; j <= i; j++)
         System.out.print(s.charAt(i));
         System.out.println();
         }
         break;
case 2: System.out.println("\n***Pattern2 Inverted Triangle***"); 
        for (i = len; i > 0; i--) 
        {for (j = 0; j < i; j++) 
        System.out.print(" " + s.charAt(j)); // inner Loop statement 
        System.out.println(); // outer loop statement 
        }
        break; 

default: System.out.println("\n Invalid choice.Please enter a valid choice");
break;
