用但不模仿并行计算，本程序是排序的，并行计算是奇偶排序-Used but does not mimic parallel computing, the process is sort of, parallel computing is the odd-even sort

pthread实现二路归并算法的并行化。对1000000个随机生成的0-99之间的数字进行排序。-Pthread implementation of the two way merge algorithm. Sorting the numbers between 1000000 randomly generated 0-99.
