Problem
To encode a message, the following actions are used: the message is written, omitting spaces, into a rectangle of a given height along the columns, and then the lines are read in the given order.
1 P R I
2 R A N
3 O M G
4G M
and then, if you choose row order 3, 1, 2, 4, get the encoded message OMGPRIRANGM.
It is required to write a program that, given the height of the rectangle and the order in which the lines are read, decodes the given message during encoding.
Input
The input contains: in the first line, the height of the rectangle H (2 ≤ H ≤ 10), in the second – the order of reading the lines (numbers are written with a space), in the third – An encoded message that is between 1 and 200 characters long. The encoded message consists of uppercase and lowercase Latin letters and numbers.
Output
The decoded message is written to the output.
