what is wrong?

[jake eum]

is this function right?

when i put (1,0,0,1,1) it return true.....

bool palindrome_2(vector<int>vec,int begin,int end){
    
       if( vec[begin] != vec[end]  ) {
        
        return false;
    }
    //return result;
    
    //cout << endl;
    //cout << vec[begin] <<" and " << vec[end] <<endl;
    palindrome_2(vec,begin+1,end-1);
    
    return true;
    
    
    
}

[sandeepdas]

alter the code as follows:


return palindrome_2(vec,begin+1,end-1);


instead of

palindrome_2(vec,begin+1,end-1);

return true;

[jake eum]

no it does no work

try 17 or other numbers

You need to stop call palindrome_2 if begin >= end.
