As you can see, some of the ranges are not correct and some are bigger than others. But this is just an example, if you want you can give a specific range in your program, that is fully up to you to decide. The intent of this exercise is for you to use the calculations you did in the `math-skills` exercise to guess the numbers.
As seen above, some of the ranges are not correct and some are bigger than others. As this is just an example, if you so wish, a specific range in your program can be given. That is fully up to you to decide. The intent of this exercise is to use the calculations you did in the `math-skills` exercise to guess the numbers.
### Testing
Your program will be extensively tested, so performance should be prioritized. Talking about testing, here is how it will work.
Your program will be extensively tested, so performance should be prioritized. Testing will work as follow:
If you guess correctly the range for the next given number, your score will be incremented based on the size of your range. In other words, the bigger your range is, the smaller your score will be. So my advice is for you to find the perfect balance between a small range and a good guess.
