The problem statement strictly says 2 words. Although what you elude to is good practice, if you know for a fact your input is two words here, you can write a strict function.

ignore this one. I refactored it

Not a bad solution, but as David said, learn the higher order methods on arrays and also, you can do this in linear time instead of O(n^2) if you use a map()/object{} to store your occurences as you go.

You traded time for space in your solutionl. Try to switch that such that you trade spcae for time such that you bring down running time but it takes a little more space.

See my solution , if you can (new here) if you want an idea

Good solution. I always forget that logical 'or' implies either or, or both are true. Time to refactor LOL

Oh Sorry. I'm newbie here and I will aware this not to do that mistake again. Also, thank you for your suggestion.And can i know that how many points are required to level up to another kyu.....

Not a kata issue, use Question label when your code doesn't work. Also, mark your post as having spoiler content when posting code like that and check how to use markdown formatting so your code keeps indentation

and output is same as the provided Example but it didn't pass....

No, it's not, your string has a trailing space you should get rid of.

New here and started today. I did not know how this platform works, thanks

We can see your solution here, no need to post it.
