Which sorting algorithm sorts the first two elements of an array before inserting the remaining elements into that sorted part of the array? None of these Insertion Selection Hash

The sorting algorithm that sorts the first two elements of an array before inserting the remaining elements into that sorted part of the array is **Insertion Sort**. ### Explanation: 1. **Insertion Sort** works by building a sorted section of the array one element at a time. 2. Initially, it considers the first element as a sorted part. 3. When the second element is encountered, it compares it with the first element and places it in the correct position, thus sorting the first two elements. 4. Then, it continues to take the next element and inserts it into the correct position within the already sorted section of the array. ### Other Options: - **Selection Sort** does not sort the first two elements before processing the rest; it selects the minimum element and places it in the correct position iteratively. - **Hash** is not a sorting algorithm; it is a data structure used for fast data retrieval. Thus, the correct answer is **Insertion Sort**.
