Question 4) Using reasoning similar to what we used for insertion sort in class, analyze the running time of the selection sort algorithm from the first homework assignment. selectionSort(arr) for startOfUnsorted in 0 to arr.length smallestInUnsorted = max value indexOfSmallest = -1 for i in startOfUnsorted to arr.length int current = arr[i] if arr[i] <smallestInUnsorted smallestInUnsorted = arr[i] indexOfSmallest = i swap arr[indexOfSmallest], arr [startOfUnsorted] Question 5) Why do all cases have the same runtime in selection sort? cost C₂ Cg time
