String getMultiplicationTable(int width)

• Description
  • Given one integer, width, generate a String representation of a multiplication table whose dimensions are width by width

Example 1

• Sample Script

  // : Given
  int n = 3;
  
  // : When
  String outcome = TableUtilities.getMultiplicationTable(n);
  
  // : Then
  System.out.println(outcome);
  

• Sample Output

    1 |  2 |  3 |
    2 |  4 |  6 |
    3 |  6 |  9 |
  

Example 2

• Sample Script

  // : Given
  int n = 6;
  
  // : When
  String outcome = TableUtilities.getMultiplicationTable(n);
  
  // : Then
  System.out.println(outcome);
  

• Sample Output

   1 |  2 |  3 |  4 |  5 |  6 |
   2 |  4 |  6 |  8 | 10 | 12 |
