Write a python function named $$arr$\_$resize$($arr$,$ capacity, isUpsizing$)$ as follows:

If isUpsizing $==$ True:

Create and initialize$*$ a new list named $$new$\_$arr$$ where it$$s length $=$ capacity $*1\mathrm{.}25$

If isUpsizing $==$ False:

Create and initialize$*$ a new list named $$new$\_$arr$$ where it$$s length $=$ capacity $*0\mathrm{.}75$

Copy the elements of $$arr$$ to $$new$\_$arr$.$

Print and return the $$new$\_$arr$$
