The neuron in my brain that is responsible for me knowing that people get tattoos of “Chinese” characters bumped into the neuron in my brain that is responsible for me knowing that ROT13 is used as a simple obfuscation cipher, leading to the idea of:<\/p>\n
“What does my tattoo mean? Oh, it is ROT13; it says ‘HOPE’.”<\/p>\n
The neuron in my brain for “funny” only half-fired, so the three hundred million neurons responsible for me being a nerd thought “Ooh! A problem! Let’s solve it with Python!”<\/p>\n
So, the challenge was: What sentence becomes another valid sentence when ROT13ed?<\/p>\n
First, I went through a wordlist (267k words) looking for ROT13 pairs. They are listed at the bottom.<\/p>\n
Then I went through and filtered out the useless ones. ERF and RES are words? <\/p>\n
Here is the filtered list:<\/p>\n
EBB=ROO
\nGEL=TRY
\nENG=RAT
\nANNA=NAAN
\nEBBS=ROOF
\nBIN=OVA
\nANT=NAG
\nHE=UR
\nBO=OB
\nENUF=RAHS
\nGREEN=TERRA
\nANA=NAN
\nENVY=RAIL
\nCHER=PURE
\nGURL=THEY
\nAHA=NUN
\nFUR=SHE
\nABBA=NOON
\nAVO=NIB
\nBAR=ONE
\nBE=OR
\nBA=ON
\nERRS=REEF
\nCEL=PRY
\nCHA=PUN
\nFUBAR=SHONE
\nBUB=OHO
\nBARF=ONES
\nBAL=ONY
\nIRK=VEX
\nART=NEG
\nARC=NEP<\/p>\n
Then, I chuckled at some randomness.<\/p>\n
But remember the challenge? Are there any sentences that only use these words?<\/p>\n
Well…<\/p>\n
AHA! THEY SHONE GREEN GEL ON ONE’S ROOF.
\nNUN GIRL, FUBAR TERRA! TRY BA-BARF EBBS.<\/p>\n
So, no, not really. None that I found. Perhaps if you were willing to break up word boundaries differently? Can you see any?<\/p>\n
