WebFeb 24, 2024 · Logic is if you add any number by 9, resulting addition of digit will result in the same number. Example: 6 + 9 = 15 then 1 + 5 = 6 (again you got 6). In case of decimal point, remove it and add resulting digits. Below code does the trick: i % 9 == 0 ? 9 : i % 9 Share Improve this answer edited Nov 29, 2024 at 17:59 answered Aug 20, 2024 at 8:42 WebCount Integers With Even Digit Sum - LeetCode Solutions LeetCode Solutions Home Preface Style Guide Problems Problems 1.
