8-5 Sorting

One of the most common applications in computer One of the most common applications in computer science is sorting—the process through which data are science is sorting—the process through which data are arranged according to their values. We are arranged according to their values. We are surrounded by data. If the data are not ordered, we surrounded by data. If the data are not ordered, we would spend hours trying to find a single piece of would spend hours trying to find a single piece of information. information.

Another common operation in computer science is Another common operation in computer science is searching, which is the process used to find the searching, which is the process used to find the location of a target among a list of objects. In the case location of a target among a list of objects. In the case of an array, searching means that given a value, we of an array, searching means that given a value, we want to find the location (index) of the first element in want to find the location (index) of the first element in the array that contains that value.the array that contains that value.
