Hi! To develop logic for solving problems effectively, it's important to have a good understanding of the functions of the language you're working with and adhere to its philosophy. Additionally, keeping a notebook and pencil handy is beneficial for understanding and sketching out the algorithm. This approach allows for a clearer visualization of the problem and its potential solutions.

Your resolution is very good, I've been trying to solve it for a long time, but I haven't come up with any ideas, what is your process for developing the logic for your problems?

It is the same solutions on me...

To keep it one-lined, I could have written a recursive function to divide by 2 and count the remainders, but was it really necessary ;)?

If that so the author should've written tests for that.

it's fast! however, according to the description: "...you have to do it without string operation..." lol
