The following routine removes the first half of the list passed as a parameter:

public static void removeFirstHalf(List<?> lst)
{
int theSize = lst. size() /2;
for( inti =0; i < theSize; i++ )
lst. remove(0);
}

(a) Why is theSize saved prior to entering the for loop?
(b) What is the running time of removeFirstHalf if lst is an ArrayList?
(c) What is the running time of removeFirstHalf if lst is a LinkedLIst?
(d) Does using an iterator make removeFirstHalf faster for either type of List?

Dean wants a quick way to look up staff members by their staff id. in cell q3, nest the existing vlookup function in an iferror function. if the vlookup function returns an error result, the text “invalid staff id” should be displayed by the formula. (hint: you can test that this formula is working by changing the value in cell q2 to 0, but remember to set the value of cell q2 back to 1036 when the testing is complete.)
