Clearly, show the first, middle, and last indexes as well as the target in every iteration. Show all the steps taken. Use the table below as a guideline with the provided format.   Instructions: Start your index at 0 Show all steps Mark the first row as header(The text will be in bold). Use the index number to show the first, last, and mid Use the floor function to find the middle element If struggling to insert a table, you may work this from a Word document and upload your work using the plus sign on the editing options.   ​First last​ mid​ 0​ 1​ 2​ 3​ 4​ 5​ 6​ 7​ 8​ 9​ target​ = 45

Short Answer: A program has the following page reference string 0122 3 4 4 1 3 3 25 66 2 4 If we allocate three page frames to the program using LRU a. Please draw a figure to show the page allocation/replacement. b. How many page faults will be generated?

How can you design and implement an efficient algorithm for sorting a large dataset with limited memory resources? Explain the different types of sorting algorithms, including comparison-based and non-comparison-based algorithms, and their strengths and weaknesses in terms of time and space complexity. Discuss various memory management techniques, such as external sorting and memory-mapped files, that can be used to optimize the performance of the algorithm. Provide a code example in a programming language of your choice to demonstrate the effectiveness of your sorting algorithm. Finally, evaluate the performance of your algorithm using appropriate metrics and discuss potential improvements or further research directions.
