Hi! I created this template: https://github.com/lorenzotinfena/competitive-go . For input it uses directly syscall.Read (I'm planning to do the same also for the output), and then I added a little setting (very little detail) that can lower the time, but increase the memory, or the contrary or keeping balanced, it uses debug.SetGCPercent .

Awesome template!
Thanks!
you can use bufio for input and output
for example 250680018
I should take a better look at it, but I think using directly syscall.Read permits you to make assumptions to the input such as ignoring errors, which improve performance, but of course in many cases these are little details.
