Every day, you look for something in your daily life. Similarly, in the case of a computer, a large amount of data is stored in the computer, and whenever a user requests data, the computer searches for that data in the memory and returns it to the user. There are primarily two methods for searching data in an array:

What is an algorithm?
Informally, an algorithm''''' is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. An ' algorithm is thus a sequence of computational steps that transform the input into the output.
What is the spelling of "programme"?
* Usage of program'' and ''programme : ** US: program is the only spelling normally used. ** UK: programme'' is used in all cases except for computer code, in which case ''program'' is generally used. Older sources may use ''programme for computer code. ** Canada: both program'' and ''programme'' are used, but ''programme is more common. ** Australia: program'' is endorsed by the Australian government, but ''programme is most common. ** New Zealand: programme'' is favoured by New Zealand dictionaries, and is endorsed by government usage; ''program is rarely seen outside the computing meaning.
