Swift for Loop statement, note not the same as before

/**

1. The old for statement can no longer be used. For example: for (int i=0; i<4; i++)

2. New way: For i in 0..<5 = [0, 5); for i in 0...5 = [0, 5]

3. The new way of reverse for I in (0..<5). Reversed () means (5, 0];for I in (0...5). Reversed () means [5, 0]
