Need help with a few functions

$//$ compares the underlying pointers for equalitys

template

bool

operator$==($const ListIterator& i$,$ const ListIterator& j$)$

$\{$

$//$ TODO $--$ be sure to not accidently make this an infinite recursive call!

$\}$

$//$ size$-$value constructor

explicit List $($size$\_$type count, const value$\_$type& value $=$ T $())$ : List $()$

$\{$

$//$ TODO

$//$ insert count copies of value into the list

$//$ NOTE: depends on default constructor working

$\}$

$//$ range constructor

template

List $($InputIt first, InputIt last$)$ : List $()$

$\{$

$//$ TODO

$//$ insert the range $[$first$,$ last$)$ into the list

$//$ NOTE: depends on default constructor working

$//$ probably depends on insert or push$\_$back working, too

$\}$
