Suppose l is a list and p, q, and r are positions. as a function of n, the length of list l, determine how many times the functions first, end, and next are executed by the following program. p : = first(l); while p < > end(l) do begin q : = p; while q < > end(l) do begin q : = next(q, l); r : = first(l); while r < > q do r : = next(r, l) end; p : = next(p, l) end;

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.)

Describe a data structures that supports the stack push and pop operations and a third operation findmin, which returns the smallest element in the data structure, all in o(1) worst-case time.

The database design steps are listed below in the incorrect order. choose the correct order number next to each step. determine the information to be stored in the database. determine the fields needed to record the data determine if there will be any repetition of data entered, and separate the fields into tables to normalize the data. create relationships to connect the tables.
