int fn0(const char *str)
{
char num[256] = {0};
unsigned char *pos = (unsigned char *)str;
while (*pos != 0 && num[*pos] == 0) {
num[*pos++] = 1;
}
return *pos == 0 ? 0 : 1;
}
{
char num[256] = {0};
unsigned char *pos = (unsigned char *)str;
while (*pos != 0 && num[*pos] == 0) {
num[*pos++] = 1;
}
return *pos == 0 ? 0 : 1;
}
