All rights reserved. | {{course.flashcardSetCount}} The insert_node method has an additional argument, node, which is the node struct we want to insert. Simple recursive algorithm. If the midpoint is larger than the value, perform binary search on right half of the array. Repeat these steps until the midpoint value is equal to the value of interest or we know the value is not in the array. For example, if you were given the equation 3x + 5 = 17, could you write an algorithm to explain to somebody how to solve for x? Compare the midpoint to the value of interest. Assume the first item is largest. An error occurred trying to load this video. Don’t feel stupid for asking. When she’s not coding, Hannah plays frisbee and thinks about how to make cities better places to live in. If we refer to mathematics, which is the field in which the term originates, we can say that algorithm is It's usually better to start with a high-level algorithm that includes the major part of a solution, but leaves the details until later. By using nodes and pointers, we can perform some processes much more efficiently than if we were to use an array. The ideas surrounding these algorithm examples permeate throughout many other algorithms . Select a subject to preview related courses: To unlock the next lesson you must be a Member.
