In this post we will revisit the implementation of a string-search algorithm developed by Richard Karp and Michael Rabin.
We visited this algorithm in this blog a few years ago. My motivation is a book that I am currently reading. As soon as I am done reading and experimenting with some more advanced algorithms, I will generate several posts associated with the book.
In the meantime, let’s refresh what the Rabin-Karp algorithm is used for and go over an implementation using the Java programming language. Continue reading “Rabin-Karp Algorithm – Revisited”
Earlier this week I ran into a description of Radix Sort. This sorting algorithm has been around for a few centuries (yes; that is not a typo). The algorithm dates back to 1887 to the work of Herman Hollerith (and yes; he was the inventor of the Hollerith Card Code for punched cards used in the past century).
This sorting algorithm is not the fastest, it requires additional space, but has been around for a long time. When you read about it, seems like it should not work; but it does. Continue reading “Radix Sort”
The use of string tests might not be a common process when testing software; perhaps it should.
So what is String Test?
String Tests are used to test software features when already integrated in the final software and before it is sent to production. When features in the software are being developed, engineers write unit tests to make sure that the different functions and classes work the way they were intended. These tests are typically white box and have reduced scope. Continue reading “String Testing”
