Hi
The solution in the link is of complexity (n*2^n))
Does anyone know any better solution ?

Re: [algogeeks] Facebook Interview question at NIT Warangal
@ankur, i think 1,2 and 2,1 would be same as set theory.. CMMIW.
following is the code..
#include stdio.h
#include stdlib.h
void print_comb(int *a, int len)
{
int tlen = len;
int i, j, k;
for (i=0;i5;i++) {
for (j=i+1; j4;j++) {
printf(%d , a[i]);
k=j;
while(tlen-1 0) {
printf(%d , a[k]);
k++;
tlen--;
}
printf(\n);
tlen = len;
}
}
}
int main(int argc, char *argv[])

int len = atoi(argv[1]);

assume that given arr[] is a character array i.e. arr[]={'1','2','3'}. for
any value of k it works
