String getRange(int stop)

• Description

  • Given an integer, stop, return a String concatenation of all integers between 0 up to and not including stop.

    Example

• Sample Script

  // : Given
  int stop = 11;
  
  // : When
  String outcome = NumberUtilities.getRange(stop);
  
  // : Then
  System.out.println(outcome);
  

• Sample Output

String getRange(int start, int stop)

• Description

  • Given two integers, start, and stop, return a String concatenation of all integers between start up to and not including stop.

    Example

• Sample Script

  // : Given
  int start = 5;
  int stop = 11;
  
  // : When
  String outcome = NumberUtilities.getRange(start, stop);
  
  // : Then
  System.out.println(outcome);
  

• Sample Output

String getRange(int start, int stop, int step)

• Description

  • Given three integers, start, stop, and step return a String concatenation of all integers between start up to and not including stop.

    Example

• Sample Script

  // : Given
  int start = 5;
  int stop = 20;
  int step = 5;
  
  // : When
  String outcome = NumberUtilities.getRange(start, stop, step);
  
  // : Then
  System.out.println(outcome);
  

• Sample Output

String getEvenNumbers(int start, int stop)

• Description

  • Given two integers, start, and stop, return a String concatenation of all even integers between start up to and not including stop.

    Example

• Sample Script

  // : Given
  int start = 5;
  int stop = 20;
  
  // : When
  String outcome = NumberUtilities.getEvenNumbers(start, stop);
  
  // : Then
  System.out.println(outcome);

String getOddNumbers(int start, int stop)

• Description

  • Given two integers, start, and stop, return a String concatenation of all even integers between start up to and not including stop.

    Example

• Sample Script

  // : Given
  int start = 5;
  int stop = 20;
  
  // : When
  String outcome = NumberUtilities.getOddNumbers(start, stop);
  
  // : Then
  System.out.println(outcome);

String getExponentiations(int start, int stop, int exponent)

• Description

  • Given three integers, start, stop, and exponent, return a String concatenation of all values, raised to the specified exponent, between start up to and including stop.

    Example

• Sample Script

  // : Given
  int start = 1;
  int stop = 4;
  int exponent = 3;
  
  // : When
  String outcome = NumberUtilities.getExponentiations(start, stop, exponent);
  
  // : Then
  System.out.println(outcome);
