Cesium基础知识讲解

（1）设计一个“简易计算器”，主要实现判断输入的表达式是否合法将中缀表达式转换成二叉表达式树。后序遍历求出表达式的值。能判断输入的表达式是否合法。 （2）用链式存储存储信息，求值时可以采用递归的思想，对表达式进行后序遍历。 （3）将操作结果保存到外部文件。((1) Design a "simple calculator" to judge whether the input expression is legitimate or not and convert infix expression into binary expression tree. The value of the expression is obtained by post-order traversal. Can judge whether the input expression is legitimate. (2) Store information in chain mode. When evaluating the value, we can use the idea of recursion to carry out post-order traversal of the expression. (3) To save the operation results to external files.)

EAN条码字体的解码算法 经常发现用PB的开发人员在问为什么用EAN的字体打出来的条码扫描枪无法扫描 其实受EAN的编码规格的限制，EAN的字体是不能直接使用的，EAN13的编码规格就不 多说了，下面给出两个函数可把条码转换为EAN字体可识别的字符串(分别对应EAN13和EAN8两种编码)-EAN barcode font decoding algorithms are often found with the development of PB in the question why the fonts EAN bar code scanning to fight out of the gun can not scan a matter of fact by the EAN coding specification limit, EAN fonts can not be directly used, EAN13 of coding specifications do not say, and given the following two functions can be converted to EAN barcode fonts can be identified by the string (corresponding to two coding EAN13 and EAN8)
