In this problem you will write a simple generator of Brainfuck ([https://en.wikipedia.org/wiki/Brainfuck](https://en.wikipedia.org/wiki/Brainfuck)) calculators.
You are given an arithmetic expression consisting of integers from 0 to 255 and addition/subtraction signs between them. Output a Brainfuck program which, when executed, will print the result of evaluating this expression.
We use a fairly standard Brainfuck interpreter for checking the programs:
* 30000 memory cells.
* memory cells store integers from 0 to 255 with unsigned 8-bit wraparound.
* console input (_,_ command) is not supported, but it's not needed for this problem.
## Input
The only line of input data contains the arithmetic expression. The expression will contain between 2 and 10 operands, separated with arithmetic signs plus and/or minus. Each operand will be an integer between 0 and 255, inclusive. The calculations result is guaranteed to be an integer between 0 and 255, inclusive (results of intermediary calculations might be outside of these boundaries).
## Output
Output a Brainfuck program which, when executed, will print the result of evaluating this expression. The program must be at most 5000000 characters long (including the non-command characters), and its execution must be complete in at most 50000000 steps.

在本题中，你需要编写一个简单的 Brainfuck（https://en.wikipedia.org/wiki/Brainfuck）计算器生成器。
你将获得一个算术表达式，由 0 到 255 的整数以及它们之间的加号/减号组成。请输出一个 Brainfuck 程序，该程序在执行时会打印出该表达式的计算结果。
我们使用一个相当标准的 Brainfuck 解释器来检查程序：
输入数据仅有一行，包含该算术表达式。表达式将包含 2 到 10 个操作数，由加号和/或减号分隔。每个操作数均为 0 到 255（含）之间的整数。计算结果保证为 0 到 255（含）之间的整数（中间计算结果可能超出此范围）。
请输出一个 Brainfuck 程序，该程序在执行时会打印出该表达式的计算结果。程序长度不得超过 5000000 个字符（包括非命令字符），且执行步数不得超过 50000000 步。

Given an arithmetic expression $ E = a_1 \oplus_1 a_2 \oplus_2 \cdots \oplus_{n-1} a_n $, where each $ a_i \in \{0, 1, \dots, 255\} $ and each $ \oplus_i \in \{+, -\} $, and the result $ R = E \in \{0, 1, \dots, 255\} $, construct a Brainfuck program that:
- Initializes a tape of non-negative integers (all zero except as needed),
- Writes the value $ a_1 $ to cell 0,
- For each subsequent operand $ a_i $ and operator $ \oplus_i $:
- If $ \oplus_i = + $, add $ a_i $ to the current result in cell 0,
- If $ \oplus_i = - $, subtract $ a_i $ from the current result in cell 0,
- Outputs the final value in cell 0 as an ASCII character (i.e., prints the byte value).
The program must compute $ R $ using only Brainfuck commands (`>`, `<`, `+`, `-`, `[`, `]`, `.`, `,`), operate within 50,000,000 steps, and be at most 5,000,000 characters long.
**Objective:** Generate a Brainfuck program that computes $ R $ and outputs it via `.`.
