( 350 ) F Squares PROGRAMMING constructive algorithms data structures graphs trees

B"There are n squares drawn from left to right on the floor. The i -th square has three integers p_i,a_i,b_i , written on it. The sequence p_1,p_2, ... ,p_n forms a permutation. Each round you will start from the leftmost square 1 and jump to the right. If you are now on the i -th square, you can do one of the following two operations: There are q rounds in the game. To make the game more difficult, you need to maintain a square set S (initially it is empty). You must pass through these squares during the round (other squares can also be passed through). The square set S for the i -th round is obtained by adding or removing a square from the square set for the (i-1) -th round. For each round find the minimum cost you should pay to end it. The first line contains two integers n , q ( 1 <= n,q <= 2 cdot 10^5 ) -- the number of squares and the number of rounds. The second line contains n distinct integers p_1,p_2, ... ,p_n ( 1 <= p_i <= n ). It is guaranteed that the sequence p_1,p_2, ... ,p_n forms a permutation. The third line contains n integers a_1,a_2, ldots,a_n ( -10^9 <= a_i <= 10^9 ). The fourth line contains n integers b_1,b_2, ... ,b_n ( -10^9 <= b_i <= 10^9 ). Then q lines follow, i -th of them contains a single integer x_i ( 1 <= x_i <= n ). If x_i was in the set S on the (i-1) -th round you should remove it, otherwise, you should add it. Print q lines, each of them should contain a single integer -- the minimum cost you should pay to end the corresponding round. Let's consider the character T as the end of a round. Then we can draw two graphs for the first and the second test. In the first round of the first test, the set that you must pass through is {1 } . The path you can use is 1 to 3 to T and its cost is 6 . In the second round of the first t"...
