  • Introduction to Recursion
    The process in which a function calls itself directly or indirectly is called recursion and the corresponding function is called a recursive function. A recursive algorithm takes one step toward solution and then recursively call itself to further move. The algorithm stops once we reach the solution

    Recursion is defined as a process which calls itself directly or indirectly and the corresponding function is called a recursive function.

  • Difference between Recursion and Iteration
    A program is called recursive when an entity calls itself. A program is called iterative when there is a loop (or repetition). Example: Program to find the factorial of a number C/C++ Code // C program to find factorial of given number #include <stdio.h> // ----- Recursion ----- // method to f

  • What is Tail Recursion
    Tail recursion is defined as a recursive function in which the recursive call is the last statement that is executed by the function. So basically nothing is left to execute after the recursion call. For example the following function print() is tail recursive. [GFGTABS] C++ // An example of tail re

  • What is Implicit recursion?
    What is Recursion? Recursion is a programming approach where a function repeats an action by calling itself, either directly or indirectly. This enables the function to continue performing the action until a particular condition is satisfied, such as when a particular value is reached or another con

    What is tail recursion? Tail recursion is defined as a recursive function in which the recursive call is the last statement that is executed by the function. So basically nothing is left to execute after the recursion call. What is non-tail recursion? Non-tail or head recursion is defined as a recur

  • Recursive Functions
    A Recursive function can be defined as a routine that calls itself directly or indirectly. In other words, a recursive function is a function that solves a problem by solving smaller instances of the same problem. This technique is commonly used in programming to solve problems that can be broken do
