Race Condition

A race condition occurs within a critical section when two or more tasks try to access and alter a shared resource simultaneously. As a consequence, the process changes to a state of inconsistency.

Question

8 Task 6: Launching Attack on 64-bit Program (Level 4)
The target program (stack-L4) in this task is similar to the one in the Level 2, except that the buffer size
is extremely small. We set the buffer size to 10, while in Level 2, the buffer size is much larger. Your goal is
the same: get the root shell by attacking this Set-UID program. You may encounter additional challenges
in this attack due to the small buffer size. If that is the case, you need to explain how your have solved those
challenges in your attack.

Please explain What is the worse-case performance of quicksort? Select the correct answer with the correct justification. Group of answer choices a. O(n*n), because during the partitioning stage it is possible that we select a 'bad' random pivot point that only sorts one item at a time. If we continuously do this over and over again, we are effectively only sorting 1 item each time. We then need to perform this pivot step n more times to sort the remaining n-1 items, thus giving us an O(n*n) complexity. b. O(n*n), because quicksort is a comparison-based sorting algorithm in which we have to compare every possible element against every other element in order to swap each element into the correct position. c. O(n*log(n)), because each time we are selecting a pivot point, on the average-case we are able to split our problem into roughly two collections, and sort half of our elements at the pivot point.
Hey there please help with code.
What would be the missing line
Use stacks to implement a postfix-to-infix translator. Until the user closes the programme, it should continually read a postfix expression and output the identical infix expression. If the postfix expression entered is incorrect, throw an exception.
Write a performance driver client program that uses insert to fill a priority queue, then does as many remove the maximum and insert operations as it can do in 1 second, doing so multiple times on random sequences of keys ofvarious lengths ranging from small to large; and prints out or plots the average numberof remove the maximum operations it was able to do.
