Additional test cases have been added.

How to pass test 15, I see only integer converted to float in my function, then back to the int64 is too late, I have lost last digit.

In addition to the remark of TurqoiseInt, y_correct seems to be wrong for test 15. I guess y_correct = 86 assumes x = 12345678987654000.

Test 15 is wrong. True number of segment in number 12345678987654321 is 80. If last digit is losted then true number become 84. In this test correct answer is 86. Maybe it is misprint?
