Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ACM-ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.
Never use someone else's code, read the tutorials or communicate with other person during a virtual contest.

C. Swap Adjacent Elements

standard outputYou have an array *a* consisting of *n* integers. Each integer from 1 to *n* appears exactly once in this array.

For some indices *i* (1 ≤ *i* ≤ *n* - 1) it is possible to swap *i*-th element with (*i* + 1)-th, for other indices it is not possible. You may perform any number of swapping operations any order. There is no limit on the number of times you swap *i*-th element with (*i* + 1)-th (if the position is not forbidden).

Can you make this array sorted in ascending order performing some sequence of swapping operations?

Input

The first line contains one integer *n* (2 ≤ *n* ≤ 200000) — the number of elements in the array.

The second line contains *n* integers *a*_{1}, *a*_{2}, ..., *a*_{n} (1 ≤ *a*_{i} ≤ 200000) — the elements of the array. Each integer from 1 to *n* appears exactly once.

The third line contains a string of *n* - 1 characters, each character is either 0 or 1. If *i*-th character is 1, then you can swap *i*-th element with (*i* + 1)-th any number of times, otherwise it is forbidden to swap *i*-th element with (*i* + 1)-th.

Output

If it is possible to sort the array in ascending order using any sequence of swaps you are allowed to make, print YES. Otherwise, print NO.

Note

In the first example you may swap *a*_{3} and *a*_{4}, and then swap *a*_{4} and *a*_{5}.
