Hi there, I am asking for a tips/tricks or a template for python competitive that does the same. For example, One tip would be to use sys.stdin.readline instead of input cause its much faster. It costed me a few contest question before I read a bunch of comments online telling me the same. Which is why I am asking, If anyone knows a good resource or template or tips please share the same. Thanks in advance.
