On visual studio you can open the project settings, select debugging
options and as command arguments put (select all configurations if you use
debug and release configurations)
< problem.in > problem.out
Where problem.in and problem.out are files in the same directory as your
cpp file, you can create them in visual studio with add new item on the
project.
You would paste the downloaded input file on problem.in and you'd upload
problem.out after running the program.
Or, you can use freopen top redirect streams, two lines of code.
