You will be given a input number (eg) x='geikm' y==1
you have to figure out the dechiper key and match it with given input and decipher it
ref=ascii(32:126); decipher_key1=[ascii(33:126) ascii(32) ]; decipher_key2=[ascii(34:126) ascii(32:33) ];
decipher_key3=[ascii(35:126) ascii(32:34) ]
output ='hello'
if y==2
input='hello'
output='geikm'
"If" and "while" are forbidden
