I've spent the best part of a day on this question, it is marked as Expert which is way above my level but I gave it my best attempt. There are about fifteen submission test cases and my solution manages to satisfy the first four. However, from there on in it hits timeouts due to performance issu...
Background
I wrote my_length class and some code. my_length can be stringified using << operator, and main() tests this.
Questions
I think operator<< can be refactored. How can I rewrite operator<< of my_length, and make it better code?
How can I make rest of code better?
Code

A solution for a small algorithmic problem. I believe tests are pretty descriptive:

def solution(lst):

stack = lst[0:1]

while(len(lst)):
nxt = lst.pop()

The world is full of interesting yearly traditions. Take for example the tomato and orange throwing events, the buffet for monkeys, and the cheese rolling festivities. With such examples of human creativity, we at Stack Overflow could not pass on this opportunity. We have created and maintained our own yearly tradition – Winter Bash!
This year we are attempting to knit our users together in our love for hats for the 7th year in a row. And this year, we’ve even added a way for you to get creative without wasting any real yarn. Starting now (December 12, 2018) and going through …

I just started Advent of Code 2018. This is exercise 2 of day 1, and I can't understand why my code is so slow (4 minutes 37 seconds, compared to 200ms for a friend who did it in Clojure with the same computer).
Basically, it accumulates integers from a provided list of ints, named input. Whenev...
