题目描述

Takahashi has a string S consisting of lowercase English letters.

Starting with this string, he will produce a new one in the procedure given as follows.

The procedure consists of $Q operations. In Operation i (1 \leq i \leq Q), an integer T_i$ is provided, which means the following:

  • If T_i = 1: reverse the string S.

  • If T_i = 2: An integer F_i and a lowercase English letter C_i are additionally provided.

  • If F_i = 1 : Add C_i to the beginning of the string S.

  • If F_i = 2 : Add C_i to the end of the string S.

Help Takahashi by finding the final string that results from the procedure.

Constraints

  • $1 \leq |S| \leq 10^5$
  • S consists of lowercase English letters.
  • $1 \leq Q \leq 2 \times 10^5$
  • T_i = 1 or 2.
  • F_i = 1 or 2, if provided.
  • C_i is a lowercase English letter, if provided.

Input

Input is given from Standard Input in the following format:

S
Q
Query_1
:
Query_Q

In the 3-rd through the (Q+2)-th lines, Query_i is one of the following:

1

which means T_i = 1, and:

2 F_i C_i

which means T_i = 2.

Output

Print the resulting string.
