- Ans.
Queue can be implemented using two stacks by maintaining the order of elements in the stacks.
Create two stacks, let's call them stack1 and stack2
When an element is enqueued, push it to stack1
When an element is dequeued, pop all elements from stack1 and push them to stack2
Pop the top element from stack2 and return it as the dequeued element
If stack2 is empty, repeat step 3
To get the front element of the queue, peek the ...
- Q2. Iven a table “student” of with columns Name and Marks. You have to write a SQL query to get the 2nd highest marks from the table. Also write a query to find the nth highest marks, where n can be any number
- Ans.
Retrieve the 2nd highest and nth highest marks from a student table using SQL queries.
Use the DISTINCT keyword to avoid duplicate marks.
For the 2nd highest marks: SELECT DISTINCT Marks FROM student ORDER BY Marks DESC LIMIT 1 OFFSET 1;
For nth highest marks: SELECT DISTINCT Marks FROM student ORDER BY Marks DESC LIMIT 1 OFFSET n-1; (replace n with the desired number)
Example for 2nd highest: If Marks are 90, 85, 90, 80, ...
- Q3. What is left join. Give example. And Full outer join?
