实验名称：操纵数值序列。

实验要求：使用随机数生成两个数值序列并输出到屏幕，并尽量使用stl已提供的功能来实现两组数值的排序、合并、找出某数值的个数、移除重复性元素、逆转排序等。-Name of experiment: manipulation of the numerical sequence.

Experimental requirements: using the random number generated two numerical sequence and output to the screen, and try to use the function of the STL has provided to realize the two sets of numerical sorting, merging, find out the number of a certain numerical, remove repetitive elements, reverse order, etc.
