Ошибка тут в том, что mid объявлен как int, а не как unsigned. Так же,
как low и high.
Если индекс массива - неотрицательное число (а это как правило именно
так, кроме сложных случаев указательной арифметики), то и тип надо
ставить неотрицательный (unsigned). Тогда приведение к unsigned будет
излишним.
