直接上代码: select case when 'workReport'=LTRIM(RTRIM(' workReport ')) then 'trim去空格成功' when 'workReport'=REPLACE(' workReport ',' ','') then 'replace去空格成功' when 'workReport'=REPLACE(' workReport ',char(ASCII(REPLACE(' workReport ','workReport',''))),'')…
一.题目:替换空格 题目:请实现一个函数,把字符串中的每个空格替换成"%20".例如输入“We are happy.”,则输出“We%20are%20happy.”. 在网络编程中,如果URL参数中含有特殊字符,如空格.'#'等,可能导致服务器端无法获得正确的参数值.我们需要将这些特殊符号转换成服务器可以识别的字符.转换的规则是在'%'后面跟上ASCII码的两位十六进制的表示.比如空格的ASCII码是32,即十六进制的0x20,因此空格被替换成"%20".再比如'#…
题目描述 请实现一个函数,将一个字符串中的空格替换成“%20”.例如,当字符串为We Are Happy.则经过替换之后的字符串为We%20Are%20Happy. 思路: 替换空格,先遍历一遍记录字符串中空格数量,算出替换后字符串长度,从后往前替换. //length为牛客系统规定字符串输出的最大长度,固定为一个常数 class Solution { public: void replaceSpace(char *str,int length) { int i,p,q; int old…
