Question

I have to submit code to one of the problems in ACM IPC and, as you may know, the time counts a lot. So, I have to read efficiently an input like this:
The first line will contain the sequence of integer values associated and the second line will contain the sequence of integer values associated with another sequence.
E.g.:

3 2 1 4 5 7 6    
3 1 2 5 6 7 4   
7 8 11 3 5 16 12 18   
8 3 11 7 16 18 12 5   
255  
255

I have to put the 1st line in an array and the second in another and pass both in a function.

How do I read and put these in C/C++? I was thinking in a C way, but my approach would have 2 while’s…
I have preference reading with scanf, but the parsing can be done as you want.

Please , help this newb!

Answer 1

Read the lines using std::getline(). Then use a std::stringstream to parse each line. As this is for a competition, you won’t be wanting actual code.
