I need help with number 2 please.

void insertionSort(int array[]) { insert(array, 1); } void insert(int[] array, int i) { if (i 0 && arrayfi - 1] > value) { array[i] = array[i] - 1]; insert = shift(array, value, i - 1); } return insert; } Draw the recursion tree for insertionSort when it is called for an array of length 5 with data that represents the worst case. Show the activations of insertionSort. insert and shift in the tree. Explain how the recursion tree would be different in the best case. Refer back to the recursion tree you provided in the previous problem. Determine a formula that counts the numbers of nodes in that tree. What is Big-Theta for execution time? Determine a formula that expresses the height of the tree. What is the Big-Theta for memory? void insertionSort(int array[]) { insert(array, 1); } void insert(int[] array, int i) { if (i 0 && arrayfi - 1] > value) { array[i] = array[i] - 1]; insert = shift(array, value, i - 1); } return insert; } Draw the recursion tree for insertionSort when it is called for an array of length 5 with data that represents the worst case.
