Answer 2

The keyword rec is required to define a recursive function

Definition of recursive function:

• Recursive functions are the functions that name themselves and are diagnosed explicitly withinside the F# language with the rec key-word.
• The rec key-word makes the call of the let binding to be had in its body.

Advantages of recursive function:

• Recursion is a programming sample this is beneficial in conditions while a task may be clearly cut up into numerous duties of the equal kind, however less complicated.
• Or while a assignment may be simplified into an smooth movement plus a less complicated variation of the equal assignment.

• It can lessen time complexity and has a rest at the wide variety of iterations( we are able to run a variable wide variety of loops ).
• It is straightforward to implement.

Thus,the keyword rec is required to define a recursive function.
