What is the goal of an algorithm that finds the minimum or maximum value in an array?
The goal is to traverse the array while keeping track of the smallest or largest value encountered so far, ultimately returning that value after checking all elements.

What is the goal of an algorithm that finds the minimum or maximum value in an array?
The goal is to traverse the array while keeping track of the smallest or largest value encountered so far, ultimately returning that value after checking all elements.
How does a standard algorithm determine if *at least one* element in an array has a particular property?
The algorithm traverses the array, and as soon as it finds an element that *does* have the property, it can immediately determine the result is true.
What does it mean to shift or rotate elements in an array?
This involves moving the elements of an array a certain number of positions to the left or right, often causing elements at one end to wrap around to the other.
How does a standard algorithm determine if *all* elements in an array have a particular property?
The algorithm traverses the array, and if it finds any single element that does *not* have the property, it can immediately determine the result is false; otherwise, it's true.
To calculate the class average from an array of test scores, what standard algorithm would you use?
You would use an algorithm that traverses the array to compute the sum of all elements, and then divide by the total number of elements.
You need to count how many students scored above 90 in an array of grades. What type of standard algorithm would you implement?
You would implement an algorithm that traverses the array and determines the number of elements having a particular property (in this case, a value greater than 90).
What is a primary use for an algorithm that accesses all consecutive pairs of elements?
This algorithm is useful for comparing adjacent elements, for example, to check if an array is sorted or to find the largest difference between neighboring values.
What is an array traversal?
An array traversal is the process of accessing each element of an array, usually in order, to perform some operation or check a condition.
How can an array traversal be used to determine the presence of duplicate elements?
An algorithm can check for duplicates by traversing the array and comparing each element to the other elements to see if any value appears more than once.
What is the result of an algorithm that reverses the order of elements in an array?
The algorithm modifies the array so that the first element becomes the last, the second element becomes the second to last, and so on.
