standard outputOne day *n* cells of some array decided to play the following game. Initially each cell contains a number which is equal to it's ordinal number (starting from 1). Also each cell determined it's favourite number. On it's move *i*-th cell can exchange it's value with the value of some other *j*-th cell, if |*i* - *j*| = *d*_{i}, where *d*_{i} is a favourite number of *i*-th cell. Cells make moves in any order, the number of moves is unlimited.

The favourite number of each cell will be given to you. You will also be given a permutation of numbers from 1 to *n*. You are to determine whether the game could move to this state.

Input

The first line contains positive integer *n* (1 ≤ *n* ≤ 100) — the number of cells in the array. The second line contains *n* distinct integers from 1 to *n* — permutation. The last line contains *n* integers from 1 to *n* — favourite numbers of the cells.

Output

If the given state is reachable in the described game, output YES, otherwise NO.
