Feature Request Slow it down! #4

I found this on your website. It's a great little tool for visual learners. However, I was curious if there is a way to slow down the visualization or maybe pause it?

At the moment, you can only stop the animation by clicking on the top bar, and then move forward or backward step by step by clicking the arrows.

But I am thinking of implementing a customized option in which the user can define your own pace. Thanks for the request, by the way!

Hello @brpapa ,

def fn(s:str,i,j,k):
    if i >= len(s):
        if k >= 2:
            return True
        return False
    currNo = 0
    for i in range(i,len(s)):
        currNo = currNo*10 + int(s[i])
        if( j == -1 or (j-currNo) == 1 ):
            if fn(s,i+1,currNo,count+1):
                return True
    return False

Getting error with this code, Can you pls identify what is going wrong , runs fine in IDE ?

fn('1234',0,-1,0)

Error response - Your code outputs the following File "", line 19, in _fn: ''

Hi @prashul,

I improved the error messages. If you run it again you will see that the count var is not defined.
