Question

Hello,

I need help with writing the sum of the odd numbers in this specific format:

1 + 3 + 5 + 7 + 9 + 11 = 36
36 = 11 + 9 + 7 + 5 + 3 + 1

So far I have:

public static void main(String[] args) {
   int a = 0;
   int original;
   int b;
   if (a <= 0){
       TextIO.putln("Max?");
      a = TextIO.getlnInt();
      original = a;
   }
   if (a%2 == 0){
       a = a-1;
   }
  
   int counter = 0;
   int sum = 0;
   while (a > 1){
       sum = sum + a;
       System.out.print(a + " + ");
       a = a - 2;
       if(a == 1){
           System.out.print(a);
           sum = sum + 1;
          
       }
   }
  
System.out.print(" = " + sum );
} // end of main method
} // end of class

When i do this i get (with 11) 11+9+7+5+3+1 = 36

import java.util.Scanner;

public class SwitchTest {
   public static void main(String[] args) {
       int a = 0;
       int original;
       int b;
       if (a <= 0){
       TextIO.putln("Max?");
       a = TextIO.getlnInt();
       original = a;
       }
       if (a%2 == 0){
       a = a-1;
       }
      
       int counter = 0;
       int sum = 0;
       while (a > 1){
       sum = sum + a;
       System.out.print(a + " + ");
       a = a - 2;
       if(a == 1){
       System.out.print(a);
       sum = sum + 1;
      
       }
       }
      
       System.out.print(" = " + sum );
System.out.print(sum + " = ");
int i = original;
while (i > 0) {
if (i % 2 == 1) {
if (i == a) {
System.out.print(i);
} else {
System.out.print(i + " + ");
}
}
i--;
}
       } // end of main method
}
