Suppose you are provided with the following function declaration in the C programming language.
int partition (int a[ ], int n);
The function treats the first element of a[] as a pivot, and rearranges the array so that all elements less than or equal to the pivot is in the left part of the array, and all elements greater than the pivot is in the right part. In addition, it moves the pivot so that the pivot is the last element of the left part. The return value is the number of elements in the left part. The following partially given function in the C programming language is used to find the kth smallest element in an array a[ ] of size n using the partition function. We assume k ≤ n
int kth_smallest (int a[], int n, int k) 

int left_end = partition (a, n); 
if (left_end+1==k) 

    return a [left_end]; 

if (left_end+1 > k) 

    return kth_smallest (____________________); 

else

    return kth_smallest (____________________); 
    } 

 
Q.
The missing argument lists are respectively
  • a)
    (a, left_end, k) and (a+left_end+1, n–left_end–1, k–left_end–1)
  • b)
    (a, left_end, k) and (a, n–left_end–1, k–left_end–1)
  • c)
    (a, left_end+1, N–left_end–1, K–left_end–1) and(a, left_end, k)
  • d)
    (a, n–left_end–1, k–left_end–1) and (a, left_end, k)

Understanding the Function
The function `kth_smallest` aims to find the k-th smallest element in an array by utilizing a partitioning approach. Here's how it works:
- Partitioning: The `partition` function rearranges the array with respect to the pivot, which is the first element. It returns the index of the pivot after positioning it in the sorted order.
- Recursive Calls: Based on the position of the pivot, the function decides whether to search in the left or right sub-array for the k-th smallest element.
Argument Analysis
The missing arguments in the recursive calls are crucial. Let's examine the correct choice (option A):
- First Recursive Call:
- `kth_smallest(a, left_end, k)`
- Here, `left_end` indicates the number of elements less than or equal to the pivot. If `left_end + 1 > k`, it means the k-th smallest element lies within the left part of the array.
- Second Recursive Call:
- `kth_smallest(a + left_end + 1, n - left_end - 1, k - left_end - 1)`
- This call searches in the right part of the array. `a + left_end + 1` points to the first element after the left part, and `n - left_end - 1` correctly adjusts the size of the right part. The `k - left_end - 1` adjusts k, as we are searching for the (k - left_end - 1) smallest element in this right part.
Conclusion
- The selected arguments in option A facilitate the correct partitioning and recursive search for the k-th smallest element. They ensure that the function correctly narrows down the search space based on the position of the pivot.
- This efficiency is key to the algorithm's performance, making option A the right choice.
