title: How to quickly write same thing to cin every time program is run?
body: <p>I'm currently using C++ and VSCode for competitive programming in USACO. Recently, they changed their input format from file input to inputting data from terminal/stdin, which is slower because I have to paste the input into the terminal every time. Is there a way to just write data to a file and have it inputted into cin every time I run my program?</p>
