- Create a simple String calculator with a method int
Add(string numbers)
- The method can take 0, 1 or 2 numbers, and will return their sum (for an empty string it will return 0) for example “” or “1” or “1,2”
- Start with the simplest test case of an empty string and move to 1 and two numbers
-
Allow the Add method to handle an unknown amount of numbers
-
Allow the Add method to handle new lines between numbers (instead of commas)
- the following input is ok:
1 2,3
(will equal 6) - the following input is NOT ok:
1,
(not need to prove it - just clarifying)
- Support different delimiters
- to change a delimiter, the beginning of the string will contain a separate line that looks like this:
//[delimiter] [numbers…]
for example//; 1;2
should return three where the default delimiter is;
- the first line is optional. All existing scenarios should still be supported
- Calling Add with a negative number will throw an exception
negatives not allowed
- and the negative that was passed. If there are multiple negatives, show all of them in the exception message - Numbers bigger than 1000 should be ignored, so adding 2 + 1001 = 2
- Delimiters can be of any length with the following format:
//[delimiter]
for example://[***] 1**_2_**3
should return 6 - Allow multiple delimiters like this:
//[delim1][delim2]
for example//[][%] 12%3
should return 6 - make sure you can also handle multiple delimiters with length longer than one char
Run the tests with:
npm run test:once
=> if you want ro run the tests only oncenpm run test:watch
=> if you want ro keep test refreshing as you code
