Sets and Arrays
Learn to program the set operations.
We'll cover the following...
Introduction to sets
In discrete mathematics, studying sets is mandatory. Why? Because set theory is only concerned with distinct numbers. Naturally, it has widespread applications in computer science.
We can translate every single property of set theory into computer programming. And, yes, with the help of simple arrays. We don’t need complex data structures, algorithms, classes, or collection hierarchies.
Set theory concepts are spread widely in computer science. We can make declarative statements in any SQL query with all types of set operations. We’ll find typical unions, intersections, differences, complements, etc.
Moreover, we can also do the same thing in our array world.
A set in discrete mathematics is a list of well-defined collections of unique integers. Are there any similarities with an array? An array is also a well-defined collection of similar quantities. It could be integers, decimal values, or even strings or characters. The main difference is an array doesn’t always contain unique items.
As a result, we can manipulate arrays in diverse ways, which was intended when the ...
