    Hello everyone,
    Currently there's a live puzzle going on from 4th of sept to 7th of Sept. It a highly anticipating and encouraging event and therefore requires basic fundamentals programming skills.

    Anyone looking forward to teaming up then ping up in private

    In short I'm a python developer, scientific computational programmer and ML enthusiast.

    Hi! I am new here, Doing the Cs50 for business professionals. I need some help with this question.

    Suppose that an engineer excitedly runs up to you and claims that they've implemented an algorithm that can sort n elements (e.g., numbers) in fewer than n steps. Give some thought as to why that's simply not possible and politely explain.

    Rom
    @rom5991
    Well if you have less than n steps, you can't check if each element is sorted and you might leave some out of orders... Right?

    hi any idea why am i facing this error?

    the line where you use the 'get_string' function is outside the main function. move this line to be inside the main function curly brackets and it should solve the problem
