Re: [algogeeks] a doubt..
Navneet can you point to some resources ? Iterative procedures are generally faster than recursion unless it is not required to fill the table completely.

Re: [algogeeks] a doubt..
Not really, time to push and pop functions from stack is not included in algorithm analysis because it would ultimately be compiler/machine dependent Also running time of algorithms is very much a theoritical concept which works for most practical purposes.

Re: [algogeeks] a doubt..
wont recursion will also be resource (time) intensive because of the multiple function call which is not observed in iterative procedures.

Re: [algogeeks] a doubt..
Recursion is the best way to write compact programs for what might seem as tedious tasks to do. Dynamic Programming is an alternate to recursion when problems possess characteristics like suboptimal substructures and overlapping subproblems. Dynamic Programming is a iterative way of doing tasks which can also be done with recursion but they are generally less time intensive. Recursion is space intensive because it takes space for storing activation blocks of recursive function calls On Tue, Jun 14, 2011 at 2:18 AM, Supraja Jayakumar wrote: > Is it right to say iteration is resource(time) intensive and recursion is > not.

Is it right to say iteration is resource(time) intensive and recursion is not. On the other hand, recursion is space intensive (with stacks) and iteration is not ?

its always better to have iterative program than recursive since iterative program doesn't rely on system stack.. but recursive program are easy to write and gives a clear view of program On Tue, Jun 14, 2011 at 1:13 AM, snehi jain wrote: > hi, > we try to implement many programs using Recursion > and its said that this is better than iterative procedure. > > if i am right then > i cant understand why is it so? > can anybody explain ... > and are there situations when iterative procedure is better than recursion. > > > Snehi > > -- > You received this message because you are subscribed to the Google Groups > "Algorithm Geeks" group. > To post to this group, send email to algogeeks@googlegroups.com. > To unsubscribe from this group, send email to > algogeeks+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/algogeeks?hl=en. > -- Regards Aditya Kumar B-tech 3rd year Computer Science & Engg.

hi, we try to implement many programs using Recursion and its said that this is better than iterative procedure. if i am right then i cant understand why is it so? can anybody explain ... and are there situations when iterative procedure is better than recursion.
