题目描述
You are given a permutation of the numbers 1,2,...,n and m pairs of positions (aj,bj) .
At each step you can choose a pair from the given positions and swap the numbers in that positions. What is the lexicographically maximal permutation one can get?
Let p and q be two permutations of the numbers 1,2,...,n . p is lexicographically smaller than the q if a number 1<=i<=n exists, so pk=qk for 1<=k<i and p_{i}<q_{i} .
输入格式
The first line contains two integers n and m ( 1<=n,m<=106 ) — the length of the permutation p and the number of pairs of positions.
The second line contains n distinct integers pi ( 1<=pi<=n ) — the elements of the permutation p .
Each of the last m lines contains two integers (aj,bj) ( 1<=aj,bj<=n ) — the pairs of positions to swap. Note that you are given a positions, not the values to swap.
输出格式
Print the only line with n distinct integers pi′ ( 1<=pi′<=n ) — the lexicographically maximal permutation one can get.
