I have some long integers called x,y;
Let us begin;
Use the way of input(x,y);
I have some long integers k(y divided by x),w(0),p(1);
While the value of p is less than the value of k plus 1 do{
    Let the value of w be the value of w plus 1;
    Let the value of p be the value of p times 2;
}
Print out w;
Print out '\n';
That is all;
Thank you so much;
