//Basic Mathematical Operations
/*Your task is to create a function that does four basic mathematical operations.

The function should take three arguments - operation(string/char), value1(number), value2(number).
The function should return result of numbers after applying the chosen operation.

Examples(Operator, value1, value2) --> output
('+', 4, 7) --> 11
('-', 15, 18) --> -3
('*', 5, 5) --> 25
('/', 49, 7) --> 7
*/

function basicOp(operation, value1, value2) {
  switch (operation) {
    case "+":
      return value1 + value2;
    case "-":
      return value1 - value2;
    case "*":
      return value1 * value2;
    case "/":
      return value1 / value2;
  }
}

Test.assertSimilar(basicOp("+", 4, 7), 11);
Test.assertSimilar(basicOp("-", 15, 18), -3);
Test.assertSimilar(basicOp("*", 5, 5), 25);
Test.assertSimilar(basicOp("/", 49, 7), 7);
