*DAILY-MINI-CHALLENGE* : ANY TEXT CAN BE STORED IN A (!VERY BIG!) NUMBER AND EACH NUMBER CAN REPRESENT ANY TEXT. CHECK IT OUT!!!

A string s = "hi" can be converted into a number x: 1) split string into characters "hi" = ['h','i'] 2) convert each character to its asci_numbr ['h','i'] = [104,105] 3) start at i = 0..s.length-1: multiply each ascii-value with (256^i) and build the sum of it 104*(256^0) + 105*(256^1) = 26984 = x Backwards: While x > 0 you have to do 1) y = x%256 2) msg += ascii_char(y) 3) x = x // 256 This returns the msg = "hi" WHAT DOES x = 1701013870 MEANS? https://code.sololearn.com/cNd0BKGghjAE/?ref=app

I'll try this too, here it is: https://code.sololearn.com/WFsgk0vg00kS/ Nice! 👍 the hi's sum is: 26984 I could call it maxi-challenge for JavaScript by the big numbers, plus planning a solution.

@Julian you got a minor mistake on your question. "hi" should be represented as 26984 in base 256. 👌

Here's my C# implementation with customizable number base:- https://code.sololearn.com/czfxMhjho33G/?ref=app *UPDATE* With reverse implementation as well 😄 LINQ One-Liner 〰 Enumerable.Range(1, str.Length).Sum(n => str[n - 1] * Math.Pow(256, n - 1));

@Sayantan wich language? ^^ if you're using js there are several librarys for 'bigint'. but you have to download most of them... https://stackoverflow.com/questions/4557509/javascript-summing-large-integers

Nice challenge mate, this would make for a pretty good encryption. Here's my attempt. https://code.sololearn.com/cgj3SlchmQS4/?ref=app
