两个升序排列的数组，合并之后仍然为升序排列。

 1 num_list1 = [2, 4, 7, 9, 11, 12]
 2 num_list2 = [3, 5, 6, 7, 8, 11, 16]

 4 size1 = len(num_list1)
 5 size2 = len(num_list2)
 6 temp = [0] * (size1 + size2)
 7 i, j, k = 0, 0, 0
 8 while i < size1 and j < size2:
 9     if num_list1[i] < num_list2[j]:
10         temp[k] = num_list1[i]
11         k += 1
12         i += 1
13     else:

22     temp[k] = num_list2[j]
23     k += 1
24     j += 1
25 print(temp)
