another way is use gets( str_buff ) and use sscanf()
and cin.get( char );

1
3
3 1 2 3
2 4 5
3 4 2 6

the first one have 2 unique type {1,3}
the second one have 1 unique type {5}
the third one have 1 unique type {6}

sum of unique = 4
and first one have half of them and get 50% so it is easy to compute the percents of others.

### Re

char ch = 255;
ch is negative one !
but the clarification said that the character codes are non-negative.
then you can use only char.

I think this method have precision error because of using the cos function but input should be compatible with output of all methods that are correct not only for the method of problemseter.
