Arranging data makes the difference
Computers also have a strict idea about the form and structure of data. When you
begin working with algorithms, you find that a large part of the job involves mak-
ing the data appear in a form that the computer can use when using the algorithm
to find a solution to an issue. Although a human can mentally see patterns in data
that isn’t arranged precisely right, computers really do need the precision to find
the same pattern. The benefit of this precision is that computers can often make
new patterns visible. In fact, that’s one of the main reasons to use algorithms with
computers — to help locate new patterns and then use those patterns to perform
other tasks. For example, a computer may recognize a customer’s spending pat-
tern so that you can use the information to generate more sales automatically.
