Recursive merge sort in python - Code Review Stack Exchange
Feb 1, 2017 · I'm very new to python, however not new to programming as I've been doing C for some time. So here is my practice of a merge sort, I looked at other questions however they were many more lines compared to mine. Which leaves me to believe I'm doing something wrong. I come here to look for best practices in python, and I mean the best of the best.
Python Merge Sort Implementation - Code Review Stack Exchange
Jul 13, 2017 · I doing some algorithm reviews and am soliciting opinions on my implementation of the Merge Sort in Python. Anything from readability to optimization is fair game. In particular, I am wondering if accessing the elements of a list using pop(0) somehow slows things down. I am doing this because I am not aware of a good way to peek into the last ...
