One of the best!
Is modifying the input really best practice?
Very readable and logical. Oh, this language design...
Super easy to read!
that's a very good question...
._.
What is being repeated that shouldn't be in this solution?
have you used
timeitto compare the performance of yourCounter()solution with this one? I personally believe that your solution could be 10X slower.Repeating code doesnt automatically ruin a solution. In this case it is actually very readable and writing this in another way would make it unclear for no reason
How could this be "best practices"? 0_o
Time complexity is O(n^2), would not consider it as 'best practices' while there are more optimal solutions (e.g. see Counter).
But useless
=~)ok i'm not the only one, I thought of this first and was like nope thats O(n)...
this is the way
