As we all know, a long time ago, the Bindian tribe lived in Belan. Their capital is surrounded by n hills, forming a circle. There is a night watchman on every mountain, guarding the block day and night.

In case of danger, the night watchman can make a fire on the mountain. One night watchman can see another night watchman's signal. If an arc connects two hills, there is no higher mountain than these two hills. For any two mountains, there are two different arcs connecting them. If the above conditions are met on at least one arc, a signal will be seen. For example, any two adjacent people are really a signal and will be seen by others.

An important feature of this watch system is that observers can see each other's signal pairs. You have to find this number high in the mountain.
