You are given positive integers $N$ and $Q$, and a string $S$ of length $N$ consisting of lowercase English letters.
Process $Q$ queries. Each query is of one of the following two types.
1 x: Perform the following $x$ times in a row: delete the last character of $S$ and append it to the beginning.2 x: Print the $x$-th character of $S$.2 x.Input is given from Standard Input in the following format:
$N$ $Q$
$S$
$\mathrm{query}_1$
$\mathrm{query}_2$
$\vdots$
$\mathrm{query}_Q$
Each query is in the following format, where $t$ is $1$ or $2$:
$t$ $x$
For each query in the format 2 x, print the answer in a single line.
3 3 abc 2 2 1 1 2 2
b a
In the $1$-st query, $S$ is abc, so the $2$-nd character b should be printed.
In the $2$-nd query, $S$ is changed from abc to cab.
In the $3$-rd query, $S$ is cab, so the $2$-nd character a should be printed.
