Question
What is the worst-case time complexity of the Quick Sort algorithm?
Solution
The worst-case time complexity of the Quick Sort algorithm is O(n^2). This happens when the pivot element picked is either the greatest or the smallest, or in simple terms, the most or least element in the array. This causes the partition to be very unbalanced, resulting in a time complexity of O(n^2). However, this worst-case scenario does not occur often if we choose the pivot element randomly.
