B'There are n nobles, numbered from 1 to n . Noble i has a power of i . There are also m "friendships". A friendship between nobles a and b is always mutual. A noble is defined to be vulnerable if both of the following conditions are satisfied: You will have to process the following three types of queries. The process: all vulnerable nobles are simultaneously killed, and all their friendships end. Then, it is possible that new nobles become vulnerable. The process repeats itself until no nobles are vulnerable. It can be proven that the process will end in finite time. After the process is complete, you need to calculate the number of remaining nobles. Note that the results of the process are not carried over between queries, that is, every process starts with all nobles being alive! The first line contains the integers n and m ( 1 <= n <= 2 cdot 10^5 , 0 <= m <= 2 cdot 10^5 ) -- the number of nobles and number of original friendships respectively. The next m lines each contain the integers u and v ( 1 <= u,v <= n , u ne v ), describing a friendship. No friendship is listed twice. The next line contains the integer q ( 1 <= q <= 2 cdot {10}^{5} ) -- the number of queries. The next q lines contain the queries themselves, each query has one of the following three formats. For each type 3 query print one integer to a new line. It is guaranteed that there will be at least one type 3 query. Consider the first example. In the first type 3 query, we have the diagram below. In the first round of the process, noble 1 is weaker than all of his friends ( 2 and 3 ), and is thus killed. No other noble is vulnerable in round 1. In round 2, noble 3 is weaker than his only friend, noble 4 , and is therefore killed. At this point, the process ends, and the answer is 2 . In the second type 3 query, the only sur'...
