Ten big walnuts is a whole lot of walnuts, that's for sure! Two walnuts is too little for anybody. How about six walnuts? Is it a small number of walnuts or a large one? The Parrot has already found an answer to this question: after eating a small amount of walnuts he wants to eat some more, while after eating a large amount of walnuts he feels satisfied. The Parrot enjoys eating and hates overeating; that's why
he wants to know a minimal number of walnuts that is enough to get satisfied.

In order to calculate this number, he conducted a series of experiments. Each experiment went like that:
the Parrot, being quite hungry, ate a number of walnuts and checked if this was enough to get himself satisfied.
Of course, if some number of walnuts is enough, any larger number will do either; vice versa, if
after eating a number of walnuts he is still hungry, no smaller number can get the parrot satisfied.
You should help the Parrot to process the results of the experiments.

### Input

The first line of the input contains an integer *n* — the number of experiments conducted by the parrot (0 ≤ *n* ≤ 100).
The following *n* lines contain descriptions of these experiments.
A description of an experiment consists of a number of walnuts eaten by the parrot (an integer from 3 to 9) and an outcome: “satisfied” in case this number was enough to get the parrot satisfied or “hungry” otherwise. It is known as a fact, that ten walnuts is always enough and two walnuts are always not enough.

### Output

Output the minimal number of walnuts that is enough to get the parrot satisfied. If the results of the experiments are inconsistent, output “Inconsistent”.
