def find(a):
if a<=0:
return 0;
for i in range(a+1):
if (2**i <= a):
c=i;
else :
return c;
b=int(input())
print(find(b))
this would be a simple and effective code i guess

i dont think we need so long one instead we can use
def find(a):
if a<=0:
return 0;
for i in range(a+1):
if (2**i <= a):
c=i;
else :
return c;
b=int(input())
print(find(b))

Hey @rahbdd thanks but there are a couple of issues with your suggestion

1. It's actually not about the size of the code but how verbose yet briefly it explains the algo. The actual code I have written is in fact only 5 lines, rest is explanation.
2. The syntax of your logic ??
3. Your code is remarkably slow compared to the proposed solution. Check out this performance analysis.

I would suggest you to look at all the other algo's in the repository. The goal of the TheAlgorithms as described by their authors is to document model beautiful, helpful and interesting algorithms using code

Thank you , I will try to modify it

Please DO NOT edit DIRECTORY.md. We have a workflow to do this for us.

Understood, I'll revert this change.
