Hi there! 👋

I'm the author of this kata, but during beta testing, the warriors decided to make it 5 kyu. If you can influence the level of this kata, I would really appreciate it! 😊

Your solution should have O(n) time complexity to pass extra large tests

Thank you for your valuable feedback! The time complexity has been added to the task description. Unfortunately, the task's difficulty level is not set by the author; it is determined by the first solvers during the beta testing phase

Thanks for the comment! The task requires algorithms with a time complexity of O(n). To ensure that slower algorithms are not used, we need some way to check this. Very large input data is used for this purpose

Just to clarify, the problem statement ensures that the cost array will always have a length equal to or greater than the value of days. This means you won't encounter test cases where the cost array is shorter than the number of days, as in the example you mentioned.

Have you observed a scenario in random tests where money=10, days=2, and cost=[7]? In Python, the cost array's length is generated to be equal to or greater than the days value

Thank you for the valuable advice! This test has been added to the code

The word 'consecutive' was put in italics to make it more noticeable

The consecutive part of the task is illustrated by the test case (10, 2, [3, 7, 6]) -> money: 10

In the written random tests, the probability of responses with “money: …” and “days: …” is approximately equal. I point this out because calculating the response for “days: …” might take longer

Hello! For JavaScript, the maximum length of the cost array is 1.5 million, and the maximum length of the days array is 300,000

Thanks a lot! Changed as suggested. (data url)

Excellent!

• Additionally, I would include the output of the number of elements in cost (length of cost) in the Extra Large Random Tests, ensuring all input data is shown in the error message
• It's better to name individual random tests differently. Instead of using 'occurred --> expected', it's preferable to use 'Small random test 1', 'Medium random test 4', and so on.
• In the basic tests, I would suggest adopting a similar approach to other languages. For instance, name the test 'Single day rental' or 'Cheapest day rental', and include the values of the variables money, days, and cost in the error message
• The value of 'days' is fixed across all 10 tests. It would be better to make it different for each individual test

Thank you for your contribution! It's been taken into account

Thanks for your remark! The word consecutive has now been highlighted in the task description
