"Software cloning is a methodology which defines that if any size of code is used apart from its original place to some another place as it is or with some modification to perform same functionality. This activity is also known as reuse of repeating code at many places instead of writing a new code. The original piece of code which is reused is called code cloning and copied form of that code is called a clone of the original. In finding of duplicated code, plagiarism detection also work pretty well but it is not applicable to the large system in finding functional clone and also it is more time consuming even at small scale which make this detection method inappropriate."
