WGU C949- Data Structures And Algorithms Exam With 100% Correct Answers 2024 Algorithm - answerA computable set of steps to achieve a desired result. Array - answerIn programming, a list of data values, all of the same type, any element of which can be referenced by an expression consisting of the array name followed by an indexing expression. Arrays are part of the fundamentals of data structures, which, in turn, are a major fundamental of computer programming Data Structure - answerThe term data structure refers to the way data is organized for use within a program. Correct organization of data can lead to simpler and more efficient algorithms. Common data structures are linked-lists, stacks, queues and trees. FIFO - answerFirst in first out is a policy that items are processed in order of arrival. A queue implements this. Insertion Sort - answerSort by repeatedly taking the next item and inserting it into the final data structure in its proper order with respect to items already inserted. LIFO - answerLast in first out is a policy that the most recently arrived item is processed first. A stack implements this. Linked List - answerA data structure in which a list of nodes or elements of a data structure connected by pointers. A singly linked list has one pointer in each node pointing to the next node in the list; a doubly linked list has two pointers in each node pointing to the next and previous nodes. In a circular list, the first and last nodes of the list are linked together. Linear Search - answerA simple, though inefficient, search algorithm that operates by sequentially examining each element in a list until the target element is found or the last has been completely processed. Linear searches are primarily used only with very short lists. Also called sequential search. merge sort - answerA sort algorithm that splits the items to be sorted into two groups, recursively sorts each group, and merges them into a final, sorted sequence. Node - answerA unit of reference in a data structure. Also called a vertex in graphs and trees. (2) A collection of information which must be kept at a single memory location. Infix Notation - answerNotation in which the operator separates its operands. E.g. (a + b) * c. Infix notation requires the use of brackets to specify the order of evaluation, unlike either prefix or postfix notations. Postfix Notation - answerReverse Polish Notation or Suffix Notation Notation in which the operator follows its operands. E.g. a + b * c represented as abc*+. Prefix Notation - answerPolish Notation Notation in which the operator comes before its operands. E.g. a + b represented as +ab. Queue - answerA data structure with first-in first-out behavior, supporting the operations enqueue (to insert) and dequeue (t
