Write a program that receives a filename as user input. The file is structured as multiple lines containing numbers separated by a single space.
For example, this would be an acceptable file:

Your program should open this file and:

1. print all its contents;


2. write the median of all numbers to a new file called
   result.txt.

IMPORTANT NOTES:

• the median is the element in the middle when you sort the values;
  
  
  
  • the median of values (2, 1, 3) is 2, because when you sort them, you get 1, 2, 3, and 2 is the value in the middle.
  
  
  
  


• you can assume there will be no empty lines;


• there might be any arbitrary number lines in the file;


• there might be any arbitrary number of elements in a single line;


• you can assume there will always be an odd number of elements.

Example 1:

If input is:

and the contents of
file1.txt
are:

you should first print the content, and then write
2
to result.txt.

Example 2:

If input is:

and the contents of
file2.txt
are:

you should first print the content, and then write
3
to result.txt.
The elements sorted are: 1, 1, 2, 3, 4, 5, 7. In this sequence, 3 is the middle value, so it is the median.
