Solution

The answer is a. They are sorted.

Here's why:

Selection sort is a simple comparison-based algorithm. The main idea behind the algorithm is dividing the input into a sorted and an unsorted region. The sorted region is built up from scratch.

Here are the steps of the algorithm:

  1. Find the minimum value in the list.
  2. Swap it with the value in the first position.
  3. Repeat the steps above for the remainder of the list (starting at the second position and advancing each time).

After each pass, the smallest remaining element is moved to its correct position. Therefore, the beginning of the array is always sorted.

Write a program to implement the Selection Sort algorithm to sort an array of integers in ascending order.Input:91 3 5 7 9 2 4 6 8Output:1 2 3 4 5 6 7 8 9Explanation:Initially, the minimum element in the array is 1. It is swapped with the first element, resulting in the array [1, 3, 8, 2, 5, 4]. Next, the minimum element in the remaining unsorted part is 2. It is swapped with the second element, resulting in [1, 2, 8, 3, 5, 4]. This process continues, and the final sorted array is [1, 2, 3, 4, 5, 8].
