char *source = argv[1];
char *dest;
char *temp;

unsigned int bitmap[8] = {0,0,0,0,0,0,0,0};
unsigned char c;
unsigned int mask;

dest = (char*)malloc(strlen(source));
temp = dest;

printf("before %s\n", source);
i=0;
while(source[i])
{
c = source[i];
mask = 1 << (c % 32);

if ((bitmap[c/32] & mask) == 0)

bitmap[c/32] |= mask;
}
i++;
}

*temp = '\0';

printf("after %s\n", dest);
}
