@B1ts I know this is an old post but still wanted to say thank you so much for your explanation! It was super helpful, especially with the log = console.log!

This is really cool,but I'll learn it later when I become an expert!

perfect!

i have no idiea ,absolute code

i had the methods but didnt know how to get the right map. great work !

I've tried both solutions on the same dataset as here, then added some random generated data also. And at the average my solution is faster (at least on my machine & my test method). But anyway due to Python3 is an interpreted language it will be slow always.
P.s. your solution has better performance than mine also, good job!

Its funny that you consider performant code the most important factor while complaining about a more performant solution than your own.

How is this working for every space when it is not replaceAll()

yes! they are so difficult to understand for beginners

yoo so did i
