题意翻译

给出一个数列,有q个操作,每种操作是把区间[l,r]中等于x的数改成y.输出q步操作完的数列.

题目描述

You are given an array $ a $ consisting of $ n $ integers. You have to process $ q $ queries to this array; each query is given as four numbers $ l $ , $ r $ , $ x $ and $ y $ , denoting that for every $ i $ such that $ l<=i<=r $ and $ a_{i}=x $ you have to set $ a_{i} $ equal to $ y $ . Print the array after all queries are processed.

The first line contains one integer $ n $ ( $ 1<=n<=200000 $ ) — the size of array $ a $ . The second line contains $ n $ integers $ a_{1} $ , $ a_{2} $ , ..., $ a_{n} $ ( $ 1<=a_{i}<=100 $ ) — the elements of array $ a $ . The third line contains one integer $ q $ ( $ 1<=q<=200000 $ ) — the number of queries you have to process. Then $ q $ lines follow. $ i $ -th line contains four integers $ l $ , $ r $ , $ x $ and $ y $ denoting $ i $ -th query ( $ 1<=l<=r<=n $ , $ 1<=x,y<=100 $ ).

输出格式

Print $ n $ integers — elements of array $ a $ after all changes are made.
