Final answer:
The algorithm used in the code snippet is Selection Sort, identifiable by the nested loops for finding and swapping the minimum element of the unsorted array part with the current index.
Step-by-step explanation:
Based on the given code snippet, the correct algorithm used is Selection Sort. The selection sort algorithm works by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning. The code snippet provided describes a generic method for sorting an array. It iterates through each element of the array, assigns the current index to min, and then iterates through the remaining elements to find the smallest (or minimal) element. It then swaps the minimal element with the current position. This process continues until the array is sorted.
The key characteristics of selection sort evident in the code are the nested loops: an outer loop to iterate through each element and an inner loop to find the minimum element in the unsorted part of the array and perform the swap.
