Show step by step please and is HCS112 coding for all parts.

Solution

A)

ORG 100 //program loaded into address 100

MOV B,#OOH //clearing accumilator B
LDA SUM //loading SUM
ADD SUM,5 //addign 5 to sum
STA SUM //saving SUM

B)

import static javax.swing.JOptionPane.*;
public class Gauss2
{
public static void main( String args [ ] )
   {
      // input n
      String prompt = \"Enter n: \";
      String input = showInputDialog( prompt );
      int n = Integer.parseInt( input );
      // calculate sum
      String output = \"\"; // start output str
      int sum = 0;        // start sum
      for ( int k = 1; k <= n; k++ )
      {
          for(int j = 1 ; j <= k; j++ ){
                sum = sum + 5 ;
           }
      }
      // output final answer
      output += \" = \" + sum;
      showMessageDialog( null, output );
   }
}

if u enter n value 5.then it prints 5+10+15+20+25=75
