题目描述

Vasya has got $ n $ books, numbered from $ 1 $ to $ n $ , arranged in a stack. The topmost book has number $ a_1 $ , the next one — $ a_2 $ , and so on. The book at the bottom of the stack has number $ a_n $ . All numbers are distinct. Vasya wants to move all the books to his backpack in $ n $ steps. During $ i $ -th step he wants to move the book number $ b_i $ into his backpack. If the book with number $ b_i $ is in the stack, he takes this book and all the books above the book $ b_i $ , and puts them into the backpack; otherwise he does nothing and begins the next step. For example, if books are arranged in the order $ [1, 2, 3] $ (book $ 1 $ is the topmost), and Vasya moves the books in the order $ [2, 1, 3] $ , then during the first step he will move two books ( $ 1 $ and $ 2 $ ), during the second step he will do nothing (since book $ 1 $ is already in the backpack), and during the third step — one book (the book number $ 3 $ ). Note that $ b_1, b_2, \dots, b_n $ are distinct. Help Vasya! Tell him the number of books he will put into his backpack during each step.

The first line contains one integer $ n~(1 \le n \le 2 \cdot 10^5) $ — the number of books in the stack. The second line contains $ n $ integers $ a_1, a_2, \dots, a_n~(1 \le a_i \le n) $ denoting the stack of books. The third line contains $ n $ integers $ b_1, b_2, \dots, b_n~(1 \le b_i \le n) $ denoting the steps Vasya is going to perform. All numbers $ a_1 \dots a_n $ are distinct, the same goes for $ b_1 \dots b_n $ .

输出格式


Print $ n $ integers. The $ i $ -th of them should be equal to the number of books Vasya moves to his backpack during the $ i $ -th step.

说明

The first example is described in the statement. In the second example, during the first step Vasya will move the books $ [3, 1, 4] $ . After that only books $ 2 $ and $ 5 $ remain in the stack ( $ 2 $ is above $ 5 $ ). During the second step Vasya will take the books $ 2 $ and $ 5 $ . After that the stack becomes empty, so during next steps Vasya won't move any books.
