Assume thаt we use Quicksоrt tо sоrt the аrrаy A with 5 elements where the initial values of the array elements (indexed from 1 to 5) are A : 2 4 5 3 1. This question tests your understanding of the algorithm by following the element-wise comparisons made in the execution of the algorithm. Here an element-wise comparison means the comparison of one element of the array with another element of the array or the key set in a particular step of the algorithm (Line 4 in Partition). Since the algorithm may move the elements of the array, you are asked to show the values of the elements being compared. The first element-wise comparison is "2 ≤ 1?" In order to answer the question correctly, you need to execute the algorithm on the given input step by step. The Quicksort algorithm here refers to the one taught in this class. (a) What is the 2nd element-wise comparison? [a] (b) What is the 4th element-wise comparison? [b] (c) What is the 6th element-wise comparison? [c] (d) What is the 7th element-wise comparison? [d]
