Thanks for ur clean Code!! But you haven't considered the case of repeating
characters in a string

You just need to make sure that the same character is never swapped to
the same position twice. Here is one way to do it.
#include stdio.h
#include string.h
void swap(char *s, int i, int j)
{
char t = s[i];
s[i] = s[j];
s[j] = t;
}
void permute(char *s, int n)
{
if (s[n]) {
int i;
@arpit : why algo subtracts 1 from each number of the input?

1) Substract 1 from each no.
2) Now after substracting 1 from each no, convert it to base n.
for example for n=6,the number 36 will be converted to 55.
@arpit : your formula for converting base 10 to base n is bit wrong , right
formula should be :-
let given base 10 no is m and we need to convert it in base n.
then base n converted no is ( (m/n) * 10) + (m%n) ie 34 base 10 in base 6
is ((34/6)*10) + (34%6) ie 54
