Show hintHide hint
Reflect on how a well-balanced partition helps efficiency.
Question 5.
Given the array [9, 4, 8, 3, 7], implement Quicksort and demonstrate the complete sorting process with all partitioning steps.
Show hintHide hint
Identify the pivot selections and result after each partition.
Question 6.
Illustrate a scenario where selecting the first element as a pivot leads to the worst-case performance.
Show hintHide hint
Look at how the partitioning occurs with each choice of pivot.
