My simple solution using regex and iterator. --------------------- Pseudocode: 1: Extract all the word chars, reverse it. 2: Declare an empty string. set an index on s starting with 0th char. if s is a word char then fetch the list of chars (which are reversed) by calling iterator, else copy the non word char. Repeat operation until len is reached. ---------------------- def format(s): import re t = '' char_list = iter(reversed(re.findall('[a-zA-Z]',s))) indx = 0 while indx != len(s): if re.match('[a-zA-Z]',s[indx]) != None: t += next(char_list) else: t += s[indx] indx += 1 return t #--------------xxx--------------

[@PahellyChakma-mz5vq]

Use 2 pointers approach to solve the problem and make sure to check if the current character is an Alphabet

[@abdulrafayakber3798]

i think you can just add these string characters reversely into array and then just convert it into string .This is an easy method let str='ab-cd' let newStr=[] for (let i = 0, j = str.length - 1; i < str.length; i++, j--) { newStr[j] = str[i]; } // Convert the array back to a string newStr = newStr.join(''); console.log(newStr)

[@ruyvieira104]

I passed those, but when i tried the "practical nodejs challenge" I failed because the question was written in such a way that it was hard to understand what the person tried to say. "the product_list payload contains a few parameters and all should be validated, and throws TypeError / RangeError / InvalidInputError to the caller if anything does not meet the specification" What exception type for what type of error? Was the function supposed to return a "product_list" ? Why, if it's asking for a single product to be "validated"? Insanely bad

​@@pratikgohil7821 I just aced their first coding interview round a hour ago, man it was a pain. stage 1: submit CV stage 2: - they asked some bunch of stupid shit questions about JavaScript and Python. - Python questions are even more painful, it asked you about the lib asyncio, thread, single thread, tests, etc. But 20/30 questions are about thread already and god it was so so painful. - JavaScript, somehow lucky to pass. stage 3: - 2 leetcode problems, they required you to write document after you finished your solutions. - the first problem is around easy-medium (for me because I solved around 250 leetcode problems so far). - the second problem is easy honestly GOD! Their IDE was so shitty, if you accidentally make an infinite loop, the compiler will just stuck. You can't even allow to use VIM because they don't have that option yet. But I heard they are scammer, so not really care if I passed or not.

Wow. You did a good job. The only thing I think you missed was you used an array sort method instead of an array reverse method, on the array with only letters. Anyways. I never would have solved this honestly. 😂

[@markmendez1014]

Very good coders fail these tests all the time because of anxiety, unclear questions or just a poor editor like the one on Turing. It does not mean you are stupid. First time I did one I was so angry because I’m a frontend dev and did not expect to be asked to write someone stupid palindrome algo lol 😂 A better way to test is to ask to solve common problems you will encounter as a developer.

[@bozzistef]

I agree with you. I have a computer science degree and I work as a frontend too. I've practiced a lot of algorithms and data structures problems since I've been in university but it still hard to take a problem like the second one if you have not been practicing recently. Also it is not correlated for a frontend position.

My solution would have been to remove the non letters and store them in a hash map with their indexes Then reverse the string and reinsert them using splice()

[@viktor8050]

You could just do this if you want to make it step by step easy, reverse the string, and loop Trough the first string and if its a letter replace its index with the reverse string index.

Also what im thinking

[@AlamKhan-yt9wd]

But insert using splice() take O(N) time. So, ultimately, it becomes O(N^2)

Can anyone confirm that Turing is a legit way to find jobs? I passed a coding challenge and a few tech stack tests, but failed the practical challenge because their IDE is utterly slow and lacks autocomplete. And I'm also starting to doubt about the quality of this service - first of all, it's kind of silly that they advertise about "U.S. companies" jobs like every developer on the planet dreams to work for a USA company, secondly their quizzes are just some low quality garbage written by a junior dev, and moreover the questions often have nothing to do with the technology itself but rather with some popular 3rd-party library. Also, KZbin is full of positive reviews published on their own channel instead of reviews from real people. that's what bugs me as well.
