Explanation / Answer
Zrrg zr ng gur cnex can be decoded to Meet me at the Park.
Write the Ascii values of Zrrg zr ng gur cnex they are as below
90 114 114 103 122 114 110 103 103 117 114 99 110 101 120
Now Subtract 13 from the above ascii values
77 101 101 90 109 101 97 90 90 104 101 86 97 88 107
M e e t m e a t t h e P a r k
So the decoded message is Meet me at the Park
Consider
01000100 01110010 01100101 01100001 01101101 01110011 00100000 01100100 01101111 00100000 01100011 01101111 01101101 01100101 00100000 01110100 01110010 01110101 01100101 00101100 00100000 01101001 01100110 00100000 01101111 01101110 01101100 01111001 00100000 01110111 01100101 00100000 01110111 01101001 01110011 01101000 00100000 01101000 01100001 01110010 01100100 00100000 01100101 01101110 01101111 01110101 01100111 01101000 00101110 00100000
Here the decoded message is Dreams do come true, if only we wish hard enough.
1) Convert the binary number to decimal
2) Convert the decimal number to ascii
Consider
R hfkklhv rg'h orpv gsv grxprmt xilxlwrov, rhm'g rg? Grnv rh xszhrmt zugvi zoo lu fh.
can be decoded as
I suppose it's like the ticking crocodile, isn't it? Time is chasing after all of us.
