这是我找到的解决方案之一。我喜欢它的紧凑性和分离性：
private static char[] characters = new char[] { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J' };// length: The length of the string created by bruteforcepublic static void PerformBruteForce(int length) { int charactersLength = characters.Length; int[] odometer = new int[length]; long size = (long)Math.Pow(charactersLength, length); for (int i = 0; i < size; i++) { WriteBruteForce(odometer, characters); int position = 0; do { odometer[position] += 1; odometer[position] %= charactersLength; } while (odometer[position++] == 0 && position < length); }}private static void WriteBruteForce(int[] odometer, char[] characters) { // Print backwards for (int i = odometer.Length - 1; i >= 0; i--) { Console.Write(characters[odometer[i]]); } Console.WriteLine();}
