That was not quite an answer to the question I asked. I'm curious what scale of implementation you have in mind. Are we talking many lines, a block, one line?

That was not quite an answer to the question I asked. I'm curious what scale of implementation you have in mind. Are we talking many lines, a block, one line? Asked another way, could that implementation be one line? Say, an implementation to logging a java exception within a catch block? Or, is the implementation something you would find for a leetcode question? Or are we talking something larger like the implementation of evaluating a mathematical formula in spreadsheet software?
