Algorithms

1. What term describes values that can only be either true or false?

• Boolean

• Algorithmic

• Intractable

• Sequential

What is/are used to determine whether code

should be run for both "IF" statements and "REPEAT UNTIL" loops?

• Events

• Conditions

• Correctness

• Pseudocode

3. Which combination of statements can be used to express algorithms?

• Iterative, sequential, and selection

• Correctness, efficiency, and clarity

• Readable, iterative, and efficient

• Selection, conditional, and Boolean

1. What type of problem cannot currently be determined or explained by an algorithm?

• Intractable problem

• Tractable problem

• Unsolvable problem

• Indefinite problem

When is a compound condition using the logical operator AND true?

• 'When the NOT operator is also used

• When either of the conditions are true

• When both conditions are false

• When both conditions are true

Which type of loop runs a set number of times?

• Repeat "n" times

• Infinite

• Repeat until

• Indefinite

Why is a "divide-and-conquer search more efficient than a linear search?

• It is less efficient with large data sets.

• You have to search all the values.

• You eliminate half the data set with each iteration.

• You only look at half the data set.

Sequential statements

• run until the user enters "done'

• run one after the other in the order given

• run only when the condition is true

• run until a loop finishes
