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.
