Write a program or algorithm , to print the Permutation of given string taking r at a time. Be commented to explain it.

Suppose , input is "alphabet" , and r is 5, then you have to print , Permutation taking 5 at a time. I can print the permutation taking all at a time ,but for doing this(taking r at a time) , complexity increases too much. Here is my approach :- 1.)Find the all the combination taking r at at a time. 2.)print all the permutation of individual combination taking all at a time. Did anyone has any other approach to this problem??

Asking or telling? A simple course should teach you how to do that.
