Hogwarts School of Witchcraft and Wizardry has a teacher whom the students call Mad-Eye. Now, Barty Crouch is hiding under this name. However, the real Mad-Eye's name is Alastor Moody, and now he is hidden in the chest!
In the code below, there is a function openChest, which should assign a real name to the madEye variable. However, this function does not work now. Change code only in this function to make renaming work for the top-level variable madEye.
