顺序表应用5:有序顺序表归并
Time Limit: 100 ms Memory Limit: 880 KiB
Problem Description
已知顺序表A与B是两个有序的顺序表,其中存放的数据元素皆为普通整型,将A与B表归并为C表,要求C表包含了A、B表里所有元素,并且C表仍然保持有序。
Input
 输入分为三行:
第一行输入m、n(1<=m,n<=10000)的值,即为表A、B的元素个数;
第二行输入m个有序的整数,即为表A的每一个元素;
第三行输入n个有序的整数,即为表B的每一个元素;
Output
输出为一行,即将表A、B合并为表C后,依次输出表C所存放的元素。
Sample Input
5 3 1 3 5 6 9 2 4 10
Sample Output
1 2 3 4 5 6 9 10
