Every recursive program must have a base case to make sure that the function will terminate. One critical requirement of recursive functions is the termination point or base case. merge sort, quick sort, etc…) result in optimal time complexity using recursion. There are other techniques like dynamic programming to improve such overlapped algorithms. The recursive Fibonacci algorithm has overlapping subproblems. It means the same computer takes almost 60% more time for the next Fibonacci number. The time complexity of calculating the n-th Fibonacci number using recursion is approximately 1.6 n. Usually, recursive programs result in poor time complexity. Solving it recursively yields an arithmetic series, which can be evaluated into N(N-1)/2.Įxercise: In a party of N couples, only one gender (either male or female) can shake hands with everyone. Assuming T N as a total shake-hands, it can be formulated recursively. Now the problem is reduced to small instances of (N-1) persons. Considering N-th person, (s)he has to shake a hand with (N-1) the person. Each person shakes hands with each other only once. Let us see how recursively it can be solved. It can be solved in different ways graphs, recursions, etc. In total how many hand-shakes would happen? In a party of N people, each person will shake her/his hand with each other person only once. Mathematically, recursion helps to solve a few puzzles easily.įor example, a routine interview question, Moreover, every recursive program can be written using iterative methods. Try to write an iterative algorithm for TOH. Towers of Hanoi (TOH) is one such programming exercise. Using the recursive algorithm, certain problems can be solved quite easily. In programming terms, a recursive function can be defined as a routine that calls itself directly or indirectly.
