Hello, christopher Minix.
Congratulations on creating your first Problem in Cody. However, your Test Suite is not sufficiently robust. Firstly, you should include at least four test cases. If you only include one test case, then submissions like Solution 1523310 will pass. Secondly, you need to either allow a tolerance in the results (within the Test Suite), or else state explicitly in the Problem Statement how results should be rounded. Please amend accordingly to improve the robustness & clarity. —DIV P.S. See Problem 44617 for further discussion.
