remove$\_$at$\_$index$($self$,$ index: int$)->$ None:

This method removes the element at the specified index in the dynamic array. Index $0$

refers to the beginning of the array. If the provided index is invalid, this method must

raise a custom $$DynamicArrayException$.$ If the array contains N elements, valid

indices for this method are $[0,$ N $-1]$ inclusive.

When the number of elements stored in the array $($before removal$)$ is STRICTLY LESS THAN

$$ of its current capacity, the capacity must be reduced to TWICE the number of current

elements. This check and capacity adjustment must occur BEFORE removal of the element.

If the current capacity $($before reduction$)$ is $10$ elements or less, reduction should not occur

at all. If the current capacity $($before reduction$)$ is greater than $10$ elements, the reduced

capacity cannot become less than $10$ elements. Please see the examples below, especially

example #$3,$ for clarification.

Future assignments will depend on this method being able to run in O$(1)$ best case
