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 = Tables.getMultiplicationTable(n);
      
  // : Then
  System.out.println(outcome);
  

• Sample Output

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

Example 2

• Sample Script

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

• Sample Output
