Исправлена опечатки реализации линрешета: вместо массива d использовался массив p и исправлено условие выхода из внутреннего цикла, где вместо d[k] * x должно быть k * x, потому что мы размечаем именно числа k * x, а не d[k] * x (контпример n = 40, k = 15, x = 3 x > d[k] - false (d[15] = 3, x = 3) x * d[k] > n (3 * 3 = 9 <= 40) =>продолжаем работу в цикле d[x * k] = d[45] - размечаем то, что не должны(n = 40))
