Which of the following are examples of algorithms? choose all that apply.
There are certain algorithms that come up again and again. In this tutorial, we will explore three of the most common: searching, sorting, and adding to/removing from a linked list. The ideas surrounding these algorithm examples permeate throughout many other algorithms . Understanding these three examples, will help us build a solid foundation so we can tackle future algorithm problems with confidence! Show
Algorithm Examples, #1: Binary SearchBinary search is an essential search algorithm that takes in a sorted array and returns the index of the value we are searching for. We do this with the following steps:
From the steps above, it is clear that our solution can be recursive. We will pass in a smaller array to our method on each iteration until our array only contains the value we are interested in. The tricky parts are indexing our array properly and keeping track of our index offset on each iteration so that we can return the index of our value from the original array. See below for our version of the binary search algorithm.
Binary search has a time complexity of Algorithm Examples, #2: Merge SortMerge sort,uses a similar “divide and conquer” methodology to efficiently sort arrays. See the following steps for how merge sort is implemented.
To implement merge sort, we will define two methods. One will take care of the splitting up of the array and the other will take care of merging two unsorted arrays back into a single sorted array. We call the dividing-up-method (
Merge Sort has a time complexity of Algorithm Examples, #3: Adding and Removing From a Linked ListThe linked list is a fundamental computer science data structure, that is most useful for it’s constant time insertion and deletion. By using nodes and pointers, we can perform some processes much more efficiently than if we were to use an array. See below for a schematic: A linked list is made up of nodes which each have a piece of data and a pointer to the next node. We represent this in Ruby by creating a struct, Node , with two arguments, :data and :next_node . Now, we just have to define two methods, 0 and 1 that take in a 2 node and a 3 of where to insert/delete. The 0 method has an additional argument, 5, which is the node struct we want to insert. We then loop until we find the location we would like to insert into or delete from. When we arrive at our desired location, and rearrange the pointers to reflect our insertion/deletion.
With a linked list, we can delete items from the middle of a collection without having to shift over the rest of the data structure in memory, like we would have to if we were using an array. By choosing the best data structure for our needs, we can reach optimal efficiency! What’s Next?These three algorithm examples are just the surface of fundamental algorithms we should know to both create efficient programs and succeed at technical interviews. Here are some more algorithms we can explore on our own to further our knowledge.
These are difficult concepts to grasp, so we just have to keep practicing and understand more algorithm examples! Other tutorials you might be interested to read:
