WGU D278 Scripting and Programming Objective Assessment Explore 160 - Practice-Ready Answer Guide != - answer - A __ b means a is not equal to b. _ - answer - _ is called an underscore. - answer - A __ b means a is less-than b. = - answer - A __ b means a is less-than-or-equal to b. == - answer - A __ b means a is equal to b. - answer - A __ b means a is greater-than b. = - answer - A __ b means a is greater-than-or-equal to b. 0-1 knapsack problem - answer - __: The knapsack problem with the quantity of each item limited to 1. abstract data type / ADT - answer - An abstract data type (ADT) is a data type whose creation and update are constrained to specific well-defined operations. Abstraction / information hiding / encapsulation - answer - Abstraction means to have a user interact with an item at a high-level, with lower-level internal details hidden from the user (aka information hiding or encapsulation). activity diagram - answer - A UML __ is a flowchart, similar to zyFlowchart, used to describe the flow of an activity or set of activities. addition / + - answer - The addition operator is +, as in x + y. agile approach / spiral approach - answer - A program can be built by doing small amounts of each SDLC phases in sequence, and then repeating, known as the agile approach (or spiral approach). agricultural age - answer - Civilization's earlier __ lasted many thousands of years. algorithm - answer - An __ is a sequence of steps that solves a problem, generating correct output for any valid input values. Algorithm efficiency - answer - __ is typically measured by the algorithm's computational complexity. algorithm time efficiency - answer - Algorithm time efficiency: The number of calculations required to solve a problem. analysis - answer - The __ phase determines the goals and requirements for a system. argument - answer - An __ is a value provided to a function's parameter during a function call. Any function input values, or __, appear within ( ), and are separated by commas if more than one. array - answer - An __ is a special variable having one name, but storing a list of data items, with each item being directly accessible. ASCII - answer - __ is a popular code for characters. assignment statement - answer - An __ assigns the variable on the left-side of the = with the current value of the right-side expression. auxiliary space complexity - answer - An algorithm's __ is the space complexity not including the input data. behavioral diagram - answer - A __ visualizes dynamic behavior of software, such as the flow of an algorithm. best case - answer - An algorithm's __ is the scenario where the algorithm does the minimum possible number of operations. binary numbers - answer - Computers can only represent two values (0 or 1), so base two numbers, known as __ ("bi" refers to two). Binary search - answer - __ is a faster algorithm for searching a list if the list's elements are sorted and directly accessible (such as an array). Divides an item into two halves, runs a test to decide in which half something lies, and repeats the binary search on that half. bit - answer - A single 0 or 1 is called a __. Boolean - answer - A __ is a type that has just two values: true or false. braces - answer - { } are __ . brackets - answer - [ ] are __ . branch - answer - In a program, a __ is a sequence of statements only executed under a certain condition. bug / debugging - answer - In a program, a problem's cause is called a bug, and troubleshooting is called debugging. byte - answer - Eight bits, like , are called a __. case sensitive - answer - Identifiers are __, meaning upper and lower case letters differ. character - answer - A __ includes any letter (a-z, A-Z), digit (0-9), or symbol (~, !, @, etc.). class - answer - A __ is a code blueprint for creating an object that is composed of data members and functions that operate on those data members. class diagram - answer - A UML __
