Answer Posted / shashanktrip
int combine(char in[])
{
int len;
char *out;
len= strlen(in);
printf("<<<<<<<<Combinations>>>>>>");
out=(char *)malloc(sizeof(char)*(len+1));
if(!out)return -1;
DoCombine(in,out,len,0,0);
free(out);
return 1;
}
void DoCombine(char *in, char *out, int len, int
recLevel,int start)
{
int i;
for(i=start;i<len;i++)
{
out[recLevel]=in[i];
out[recLevel+1]='\0';
printf("\n%s\n",out);
if(i<len-1)
DoCombine(in,out,len,recLevel+1,i+1);
}
}
