Swap Elements

Challenge Description:

You are given a list of numbers which is supplemented with positions that have to be swapped.

Input sample:

Your program should accept as its first argument a path to a filename. Input example is the following

1 2 3 4 5 6 7 8 9 : 0-8
1 2 3 4 5 6 7 8 9 10 : 0-1, 1-3

As you can see a colon separates numbers with positions.
Positions start with 0.
You have to process positions left to right. In the example above (2nd line) first you process 0-1, then 1-3.

Output sample:

Print the lists in the following way.

9 2 3 4 5 6 7 8 1
2 4 3 1 5 6 7 8 9 10
