$1$ var class $=["$Ann$",$ "Charles", $"$Ed$",$ "Esther", "George", "India", "Marissa", "Nigel",

$2$ var newStudent $=$ "Fernando";

insertItem$($class$[4],$ newStudent$)$;

insertltem$($class$,5,$ newStudent$)$;

appendltem$($class$,$ newStudent$)$;

appendltem$($class$,4,$ newStudent$)$;

insertItem$($class$,4,$ newStudent$)$;
