👉 In programming, a quadruplet is a set of four distinct elements. For example, in the set [1, 2, 3, 4], the quadruplets are [1, 2, 3, 4] (which are all distinct), and [1, 2, 3, 5] (which are not).
👉 The term "quadrupled" is commonly used to describe something that has been doubled or tripled in number. For example, if you were doubling a number and then adding three more, it would be described as "twice doubled." Additionally, if you are tripling a number and then multiplying by three again, it would be described as "tripled."
👉 The term "quadruple" is a term used in mathematics to describe a number that has four digits. For example, 1234 or 5678 are examples of quadruples. The word "quad" means four and "do" means one or more. So "quad" can be read as "four plus one".
