快速排序的递归解演示，用20个字符串代表20个数，显示每次分组结果，延时10000。如果在你的机子上太快，可以加长延时。-rapid sequencing of recursive solution demonstrations, with 20 representatives of 20 string number, the results show that each packet, Delay 10000. If your machine on too fast, it could be Long Time Delay.

用vc对信号进行存储因为数字表示可以有冗余数据。通过冗余数据的信息，即使传输过程中信号发生严重变化，也可以恢复原来的信号。因此数据信号被广泛使用：通讯、领航、医药、声音处理、计算机等-With vc the signal that can be stored as digital data have redundancy. Redundant data through the information, even if the transmission signal a serious change, you can revert to the original signal. Thus data signals are widely used: communications, navigation, medicine, voice processing, computer, etc.
