Consider the Tree Sort algorithm in which sorting is achieved by placing all elements to be sorted into a binary search tree and then taking the in-order traversal of the tree. AVL Tree Sort places all elements into an AVL binary search tree and then takes the in-order traversal of the tree. Which of the following statements are true about these sorts? A. Tree Sort and AVL Tree Sort both perform well on input that is already in nearly sorted order. B. The best case time complexity of Tree Sort is O(n log n) C. The worst case time complexity of AVL Tree Sort is ?(n). D. The best case space complexity of Tree Sort is 0(n) E. The best case space complexity of AVL Tree Sort is?

Write a program that performs a simple n-body simulation, called "jumping leprechauns." this simulation involves n leprechauns, numberd 1 to n. it maintains a gold value g_i for each leprechaun i, which begins with each leprechaun starting out with a million dollars worth of gold, that is, g_i = 1000000 for each i = 1,. in addition, the simulation also maintains, for each leprachaun, i, a place on the horizon, which is represented as a double-precision floating point number, x_i. in each iteration of the simulation, the simulation processes the leprachauns in order. processing a leprachaun i during its iteration begins by computing a new place on the horizon for i, which is determined by the assignment:
