문제

The Large Wood Database is created to securely store and paint any existing tree. Update for LWDB provides new functionality, so it is time to think over the graph theory. A weighed tree is stored in the LWDB. In the query language for LWDB Management System (LWDB MS) two types of queries are available:

1. <<1ドル$ $v$ $d$ $c$>> --- paint all tree-vertices at the distance not exceeding $d$ from the vertice $v$ in color $c$. Initial color for any vertices is 0ドル$.
2. <<2ドル$ $v$>> --- return the color of the vertice $v$.

It is required to prototype LWDB MS and respond to all user’s queries.

입력

The first line contains an integer $N$ (1ドル \le N \le 10^5$) --- the number of tree vertices. The following N-1 lines contain the description of branches, three numbers in each line $a_i,ドル $b_i,ドル $w_i$ (1ドル \le a_i, b_i \le N,ドル $a_i \ne b_i,ドル 1ドル \le w_i \le 10^4$), where $i$-th branch with weight $w_i$ connects vertices $a_i$ and $b_i$. The next line contains integer Q (1ドル \le Q \le 10^5$) --- number of queries. In each of Q following lines there are two types of queries:

1. Numbers 1, $v,ドル $d,ドル $c$ (1ドル \le v \le N,ドル 0ドル \le d \le 10^9,ドル 0ドル \le c \le 10^9$).
2. Numbers 2, $v$ (1ドル \le v \le N$).

Input numbers are integers.

출력

For each second type query output the color of requested vertice in a separate line.
