Answer / Ateev Sharma
The use of a recursive function is necessary when dealing with problems that can be broken down into smaller, simpler versions of the same problem. This method allows for efficient problem-solving by avoiding the need to write loops and if-else statements for every possible iteration. However, it's crucial to ensure that the base case is defined to avoid an infinite loop. When recursion functions are declared inline, they are expanded in-place, eliminating the overhead of function calls.
