Given is the IntNode class that represents an element in a linked list, and the IntList class that represents a linked list (at the end of the question). Add a method signed to the IntList class: public void selectionSort() The method will sort the list in ascending order using a selection sort algorithm. The algorithm: find the smallest number in the list and replace it with the first number. Then find the second smallest number in the list and replace it with the second number. Then find the third smallest number in the list and replace it with the third and so on.
