Using methods from the List ADT, write a method called bringToFront that moves the current element to the beginning of the list.

For example, if your method were applied to the list $(4,5,6$:$|),$ it would be changed to $($:$4,1,2,3,5,6$:$).$

$($Recall$,$ in a method, the keyword this refers to the object on which the method is called.$)$
