On the very first one it has "if ((x & 1) == 0) {" Instead of doing the compare to 0 you need to let the following code be run second because all you need to do is and x and 1. if it is zero that would be false and it falls through and runs the code you have moved to the bottem. If it is not zero you move the code from the else up and run it.
