Algorithm efficiency typically measured by the algorithm's computational complexity Computational complexity the amount of resources used by the algorithm. The most common resources considered are the runtime and memory usage. runtime complexity a function, T(N), that represents the number of constant time operations performed by the algorithm on an input of size N Space-complexity (of an algorithm) a function, S(N), that represents the number of fixed-size memory units...

Array A data structure that stores an ordered list of items, with each item is directly accessible by a positional index. Linked List A data structure that stores ordered list of items in nodes, where each node stores data and has a pointer to the next node. Bianary Search Tree A data structure in which each node stores data and has up to two children, known as a left child and a right child. Hash Table A data structure that stores unordered items by mapping (or hashing)...

inserting a new item at the beginning it causes no shift to the data what is an advantage of a linked list over an array?n N In the worst case, inserting a new node into a tree with N nodes requires how many comparisons? reference count A _____________is an integer counter that represents how many variables reference an object. When an object's reference count is 0, that object is no longer referenced. Branching directs a program to execute either one group of st...
