【MX-J30-T4】「FDOI-R1」结婚旅行

Background

Little P and Little L have just gotten married. To celebrate their marriage, they decided to take an unforgettable honeymoon trip in Country X.

Problem Description

Country X has nn cities, numbered from 11 to nn, connected by n−1n-1 bidirectional flight routes. Any city can be reached from any other city directly or indirectly via these routes.
Little P and Little L start from city 11. They planned mm travel routes in advance, and these routes are divided into CC colors. The ii-th route is the unique simple path starting at 11 and ending at kik_i, and its color is cic_i (1≤ci≤C1 \le c_i \le C).
They will make several trips. In each trip, pip_i routes are given (the same route may be chosen repeatedly). For one trip, they want to visit routes of only tit_i colors, and for routes of other colors, the total number of occurrences in this trip does not exceed ziz_i.
To achieve this goal, for each selected route SS, if and only if the endpoint of route SS is an ancestor or a descendant of the endpoint of another route TT in the tree (that is, route SS is a prefix of TT, or TT is a prefix of SS), SS can be replaced by TT. Each route in each trip can perform at most aia_i such operations.
Now Little P and Little L want you to tell them whether, for each trip, they can meet their requirements.

Formal statement

You are given a tree with nn nodes and CC colors. Initially there are no routes. First, mm routes are given. Each route is the simple path starting at 11 and ending at kik_i, and its color is cic_i. Then qq operations are given, with two types of operations.

  1. Modification: Add a route with start point 11, end point kik_i, and color cic_i, defined as above.

  2. Query: You are given pip_i routes and tit_i desired colors. Each route can perform at most aia_i operations. An operation converts the current route into another colored route, such that the current route is a prefix of the other route, or the other route is a prefix of the current route (if you do not understand the definition of "prefix", please refer to the statement above).
    Determine whether after conversions, it is possible that at most ziz_i routes do not have any of the desired colors.

Input Format

The first line contains three integers n,m,Cn, m, C.

The next n−1n-1 lines each contain two integers u,vu, v, indicating there is a flight route between cities uu and vv.

Let cntcnt have the initial value mm, and let cntcnt denote the current total number of routes. The next mm lines each contain two integers ki,cik_i, c_i, indicating the endpoint and the color of the ii-th route.

The next line contains one integer qq.

The next qq lines each describe one operation:

If di=0d_i = 0, it indicates a query.
Then the next line contains four integers pi,zi,ti,aip_i, z_i, t_i, a_i.
The next line contains pip_i integers, indicating the indices of the routes selected for this trip (may contain duplicates).
The next line contains tit_i integers, indicating the route colors that Little P and Little L want to visit (it is guaranteed that these colors exist).

If di=1d_i = 1, it indicates that a new route is found.
Then the next line contains two integers ki,cik_i, c_i. The new route index is cnt+1cnt+1, and then cntcnt increases by 11.

Output Format

Output several lines. For each query, output one line with one string: if there is a solution, output Yes, otherwise output No.

Hint

Sample Explanation 1

Query 11: After replacing route 22 with route 33, the requirement is satisfied.

Query 22: Route 11 cannot be changed to color 33.

Query 33: Because there is no route that Little P and Little L like, there must be one route they do not like, but zi=1z_i=1, so the requirement is satisfied.

Constraints

Test Point ID Constraints Special Property Score
1∼31 \sim 3 1≤n≤20001 \le n \le 2000 No special restrictions 1212
4∼94 \sim 9 No special restrictions A 2424
10∼2510 \sim 25 No special restrictions 6464

Special Property A: It is guaranteed that there is no di=1d_i=1. It is guaranteed that the tree degenerates into a chain.

For 100%100\% of the testdata:

1≤n,m,q,pi≤2×1051 \le n, m, q, p_i \le 2 \times 10^5

0≤zi≤1090 \le z_i \le 10^9

1≤u,v,ki≤n1 \le u, v, k_i \le n

0≤di≤10 \le d_i \le 1

1≤ci,ti≤C≤101 \le c_i, t_i \le C \le 10

0≤ai≤100 \le a_i \le 10

Let DD be the total number of routes selected across all cases with di=0d_i=0. Then 1≤D≤2×1051 \le D \le 2 \times 10^5.

Because the input size of this problem is large, a fast input template is provided.

inline int read() {
    int x = 0, f = 1;
    char ch = getchar();
    while (ch < '0' || ch > '9') {
        if (ch == '-') f = -1;
        ch = getchar();
    }
    while (ch >= '0' && ch <= '9') {
        x = (x << 3) + (x << 1) + (ch ^ 48);
        ch = getchar();
    }
    return x * f;
}
