A c code for this is:
int main()
{
int a[2] = {0};
char str[50];
int i,ind=0;
scanf ("%s", str);
for(i=0;i<strlen(str);i++)
{
if(str[i]>='a' && str[i]<='z')
{
if(!(a[0] & 1<<str[i]-'a'))
{
a[0] = a[0] | 1<<str[i]-'a';
str[ind]=str[i];
ind++;
}
}
else if(str[i]>='A' && str[i]<='Z')
{
if(!(a[1] & 1<<str[i]-'a'))
{
a[1] = a[1] | 1<<str[i]-'a';
str[ind]=str[i];
ind++;
}
}
}
str[ind]='\0';
printf("%s\n",str);
return 0;
}
is it fine 2 use 2 integers for this? or not allowed??
