You are given a string $s$ consisting of $n$ lowercase Latin letters.

You have to remove at most one (i.e. zero or one) character of this string in such a way that the string you obtain will be lexicographically smallest among all strings that can be obtained using this operation.

String $s = s_1 s_2 \dots s_n$ is lexicographically smaller than string $t = t_1 t_2 \dots t_m$ if $n < m$ and $s_1 = t_1, s_2 = t_2, \dots, s_n = t_n$ or there exists a number $p$ such that $p \le min(n, m)$ and $s_1 = t_1, s_2 = t_2, \dots, s_{p-1} = t_{p-1}$ and $s_p < t_p$.

For example, "aaa" is smaller than "aaaa", "abb" is smaller than "abc", "pqr" is smaller than "z".


-----Input-----

The first line of the input contains one integer $n$ ($2 \le n \le 2 \cdot 10^5$) — the length of $s$.

The second line of the input contains exactly $n$ lowercase Latin letters — the string $s$.


-----Output-----

Print one string — the smallest possible lexicographically string that can be obtained by removing at most one character from the string $s$.


-----Examples-----
Input
3
aaa

Output
aa

Input
5
abcda

Output
abca



-----Note-----

In the first example you can remove any character of $s$ to obtain the string "aa".

In the second example "abca" < "abcd" < "abcda" < "abda" < "acda" < "bcda".
