+# number-recognize
+## description
+阿比多斯学院的智能机有一种特殊的识别系统，可以识别算式。你需要复现这种识别系统的一小部分功能。可以识别出的算式中包含e123456789+-十二种符，而你需要算出算式的内容。
+
+每个待识别算式的构成是这样的:待识别算式由五行字符串表示，这些字符串由空格和小写字母x组成。多个×共同拼成0123456789+-十二种字符之一(所有字符样例在题目下方给出)。每个0123456789+-字符之间由至少一列空格分开。
+
+## Input
+五行，不超过一百五十列，由小写字母x和空格组成的待识别算式。过程中涉及到的量均在int范围以内。每个字符的所占区域(在字符样例部分，用小数点表示出)不会贴在一起。
+
+## Output
+一行一个整数，表示识别出的算式，经过计算得到的结果。
+
+## Example
+### Input
