Question

How many different string can be made by recording the
letters of the words "DISCRETE".​

Answer 1

Step-by-step explanation:

In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. The latter may allow its elements to be mutated and the length changed, or it may be fixed (after creation). A string is generally considered as a data type and is often implemented as an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding. String may also denote more general arrays or other sequence (or list) data types and structures.

Strings are applied e.g. in Bioinformatics to describe DNA strands composed of nitrogenous base
