what is meant by:

'Inner entrance of apostrophe symbol (ASCII 39) into string or template is encoded by double apostrophe symbol' ?

does it mean we have to parse this way even when 39 is encountered? or 39 can't appear ?

i take input like:
string dummy;
unsigned char ch;
cin>>ch;
while(cin>>ch&&ch!=39){
       ........
}
cin>>dummy;
while(cin>>ch&&ch!=39){
       ........
}

but this gets me WA #1

when i include this:
if(dummy!="like") while(true);

this gets me TLE #1

i don't know what's going wrong !

please help me. thanks in advance.

the problem statement is wrong or at least the english is :(

my assumption that 39 may appear was correct and got ac finally. The reason why char gets ac is 128 to 255 are mapped to unique negative values. so unsigned not needed :)
