<b>Subject:</b> [VicPiMakers Projects] Jim's Challenge - Output 10 (caesar cipher)</font>
<div> </div>
</div>
<div>
<div dir="ltr">
<div>I'm looking for clarification on output 10 - caesar cipher problem.<br>
</div>
<div><br>
</div>
<div>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.<br>
</div>
<div><br>
</div>
<div>Reasoning:</div>
<div>- "BIOPSY" will work for the 12 integer input that leads to "HOUVYE", but it will not work for any 12 random integers.
<br>
</div>
<div>- You'd have to reverse engineer your integers starting from "BIOPSY" to get a valid set of 12 integers.<br>
</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>I'm curious how other folks solved this one.</div>
