I have the same problem:
test no. 5, wrong answer.
(Sorry, i don't know english well)
Я запихнул свой алгоритм в циклы for, ввод всех возможных значений, вывод.
Просмотрел всё вручную, нет ошибок!

Carefully read the condition.
Visitor chooses a side in such a way that the number of people over whose feet he will stumble will be minimal.
It is not always the shortest path.

Внимательнее читайте условие.
Зритель выбирает сторону так, чтобы споткнуться о меньшее число людей.
Это не всегда наикратчайший путь.
