POLQUERY  Police Query
To help capture criminals on the run, the police are introducing a new computer system. The area covered by the police contains N cities and E bidirectional roads connecting them. The cities are labelled 1 to N. The police often want to catch criminals trying to get from one city to another. Inspectors, looking at a map, try to determine where to set up barricades and roadblocks.
The new computer system should answer the following two types of queries:
1. Consider two cities A and B, and a road connecting cities G_{1} and G_{2}. Can the criminals get from city A to city B if that one road is blocked and the criminals can't use it?
2. Consider three cities A, B and C. Can the criminals get from city A to city B if the entire city C is cut off and the criminals can't enter that city?
Write a program that implements the described system.
Input
The first line contains two integers N and E (2 ≤ N ≤ 10^{5}, 1 ≤ E ≤ 5*10^{5}), the number of cities and roads. Each of the following E lines contains two distinct integers between 1 and N – the labels of two cities connected by a road. There will be at most one road between any pair of cities.
The following line contains the integer Q (1 ≤ Q ≤ 10^{5}), the number of queries the system is being tested on. Each of the following Q lines contains either four or five integers. The first of these integers is the type of the query – 1 or 2.
If the query is of type 1, then the same line contains four more integers A, B, G_{1} and G_{2} as described earlier. A and B will be different. G_{1} and G_{2} will represent an existing road.
If the query is of type 2, then the same line contains three more integers A, B and C. A, B and C will be distinct integers.
The test data will be such that it is initially possible to get from each city to every other city.
Output
Output the answers to all Q queries, one per line. The answer to a query can be da (yes) or ne (no).

The sample case has 5 queries. sample output has 4 outputs. and the current order of output is wrong as well. The setter need to correct it.
