Condition: The domain of the function you wish to define recursively must be a set defined recursively. Therefore all the c programming questions are also separated by the categories. endstream >> Recursionis a technique for solving a large computational problem byrepeatedly applying the same procedure(s) to reduce it to successively smallerproblems. /Filter /FlateDecode • A recursive algorithm uses itself to solve one or more smaller identical problems. Write a JavaScript program to calculate the factorial of a number.
