Quiz: Algorithms Mock Tests on Recursion

Quiz: Algorithms Mock Tests on Recursion This quiz contains information about Algorithms Recursion. Recursion in computer science is a method of solving a problem where the solution depends on solutions to smaller instances of the same problem. Such problems can generally be solved by iteration, but this needs to identify and index the smaller instances at programming time.
What is recursion example? Recursion is the process which comes into existence when a function calls a copy of itself to work on a smaller problem. Any function which calls itself is called recursive function, and such function calls are called recursive calls. ... For Example, recursion may be applied to sorting, searching, and traversal problems.
How does recursion work? A recursive function calls itself, the memory for a called function is allocated on top of memory allocated to calling function and different copy of local variables is created for each function call. ... Let us take the example how recursion works by taking a simple function.
