Consider an undirected graph that consists of nodes and edges. There are two types of events that can happen:
- A new edge is created between nodes and .
- An existing edge between nodes and is removed.
Your task is to report the number of components after every event.
Input
The first input line has three integers , and : the number of nodes, edges and events.
After this there are lines describing the edges. Each line has two integers and : there is an edge between nodes and . There is at most one edge between any pair of nodes.
Then there are lines describing the events. Each line has the form " " where is 1 (create a new edge) or 2 (remove an edge). A new edge is always created between two nodes that do not already have an edge between them, and only existing edges can get removed.
Output
Print integers: first the number of components before the first event, and after this the new number of components after each event.
