The select statement to this question can be defined as below:
Statement:
SELECT first_name, last_name,
line1, city, state, zip_Code
FROM Customers JOIN Addresses ON
Customers.CustomerID = Addresses.CustomerID
WHERE Customers.EmailAddress = '[email protected]'.
Explanation:
Select declaration produces the data as a result of data set from more than one table. This statement collects 0 or even more rows from table, It also provides the view of the table.
- In the above statement first, we select table columns, that are given in question then we select table and join the columns by using where clause condition.
- This condition will return the columns with there values.
Answer:
One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.
Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).
Dequeueing would be:
- For all items in stack1: pop them from stack1 and push them in stack 2.
- Pop one item from stack2, which will be your dequeue result
- For all items in stack2: pop them from stack2 and push them in stack 1.
Hope it makes sense. I'm sure you can draw a diagram.
