Can’t that (below)be rewritten...it makes me “hear” those filthy books stories’...it sounds scary. De-crypt? And people taken “out”...sorry, but this is hard core shit...it’s terrifying:( always back to that Book, filthy:(

“The above method requires human intervention in order to recognize meaningful words during the decryption process. Why not write code to remove the human out of the loop? Hopefully, that explains why the string “BIOPSY” was a good choice for Challenge”

Isn’t input/output simply entering and exiting? And if so, e and x is kind of suggestively sexy, (double entendres style:) or is this stupid?

And

Here’s where things get interesting 🤔 input/out for food and such...food in / poo out:)

But for yummy sexy “stuff” then, it’s enter/exit...going to a store, being intimate, going for dinner, inviting extraterrestrials over:) would all be enter/exit (or prettier words?] just things like this? And these enter exit code placement would be our sentries, of sorts?

Is “biopsy” really a “love” word, I mean, really? Couldn’t we use a nicer word? A double entendres type of word, maybe? Fun:)

I don’t know what it means, in this context, so, I have no ideas to offer but 💡 Do You?

Besides someone could “biopsy” our “foundation” and we want a solid foundation, right? Rock solid or diamond 💎 solid, kind of thing... .

Ok, thanks.

Then there are two inputs; not just the data array. Question 10 implied a second input will be provided.

Hi Patrick,
Here is the last sentence of the comment I posted today at 2:31 PM
"The final test data will include a new string not “BIOPSY”.

Hello Jim,

Your instructions are unclear and we're just asking you to clearly address the issue.

If you want our code to output the key used then either we assume the word is the same or your next update also provides a new word in addition to a new byte array.

Which is it?

Craig, Patrick, Greg & Others,

Note that the string “BIOPSY” is not part of the input data but included in the description of Output#10 in order to simplify things. If “BIOPSY” appears in your code, you have created an implicit input to simplify things. The final test data will include a new string not “BIOPSY”.

Consider the implication of not having known the plaintext “BIOPSY”. One  solution would be to write separate code (not part of the solution to Challenge1) that sequentially reverses the encryption process. Why not do so and then just print 6 for Output #10?

The above method requires human intervention in order to recognize meaningful words during the decryption process. Why not write code to remove the human out of the loop? Hopefully, that explains why the string “BIOPSY” was a good choice for Challenge 1.

Nice one Eileen! Solving it in Scratch sounds like a challenge.

Has anyone considered trying it in a pure functional language?

Hey everyone,

Just solved challenge #1 using Scratch. Hope the new ‘Test’ data will work just as well. Intend on showing you what I did at the end of my presentation on Oct 24.

Have a nice week,

Also, a language of love would have to be, would need to, continually fortified in order for it to remain foundation-ally strong, right white lights? And, its strength comes from our ever evolving understanding/feeling/sensing/knowing of what our hearts are truly capable of and then, illustrating this in the majesty that WILL be our code that You all create, see?

Also, just a thought, what about that bit coin spin around the world tor thing...if we built our foundation on something like this wouldn’t this keep any nasty extraterrestrials at bay but wouldn’t it also, keep us ALL contained herein, safely.

I agree it's not that clear.

If the goal to be able to simply run the existing code on new input bytes then yes, "BIOPSY" is always the decrypted word since the byte array is the only given input. If the word changes, that hasn't been specified where that input would come from. So, either it doesn't change or the description of the second input is missing.

But using a hard-coded word doesn't sound terribly interesting to code up. You could still write your key finding function to accept two strings of equal length and output the required caesar key. Then for question #10, call it with the word you extract from the input array and the hard-coded target word and write the output key. Then the problem is hard-coded but your code is more generic.

For me, the confusion is that we're intended to write code to derive the cipher key value. I did this and came up with an answer, but this key is only relevant "HOUVYE" / "BIOPSY".

So should I take this key and make it a constant for future inputs / encryptions? That's what I ended up doing with my final code submission.

I took out the code that solved the problem because unused code seems like lint to me, but maybe I should put it back to show how I did it.

Hi Patrick,
 Yes, you can look at only the first character of the string and use it to get the key. Comparing all characters as the advantage of catching errors in encryption/decryption. The code is just as short using  "compare strings"  of your particular language.

In C int strcmp (const char* str1, const char* str2);, in C++ int CompareText(const AnsiString S1, const AnsiString S2); Pascal ( Delphi) function CompareText(const S1: string; const S2: string): Integer;

Aside: The purpose of the final test data is to see if your outputs are correct when you run your code with the new data. It should work the first time with no changes in the actual code.

Ok.

Now, if u could think in terms of front back / embroidery and its front back...
So, above is a code interface? But where is the back front and back? Front would be the website, right? So, when I do online shopping, that’s the front. Where is the back view of the front of the website?

Another example, when writing in ink it can show through the backside when held to the light, kind of thing is what I’m trying to understand? Where’s that on the internet?

Subject: [VicPiMakers Projects] Jim's Challenge - Output 10 (caesar cipher)

I'm looking for clarification on output 10 - caesar cipher problem.

Is the intent to calculate the caesar cipher key value OR is the intent to encrypt the string with a pre-determined key? Initially I thought the question was to discover the cipher key value, but on reflection this seems fragile.

Reasoning:
- "BIOPSY" will work for the 12 integer input that leads to "HOUVYE", but it will not work for any 12 random integers.
- You'd have to reverse engineer your integers starting from "BIOPSY" to get a valid set of 12 integers.

I solved it both ways, but posted only the 2nd solution to github because only the 2nd solution will work for a random set of 12 integers.

I'm curious how other folks solved this one.
