1.单纯的Unicode 转码 String a = "\u53ef\u4ee5\u6ce8\u518c"; a = new String(a.getBytes("UTF-16"),"Unicode"); 2.String 字符串中含有 Unicode 编码时,转为UTF-8 public static String decodeUnicode(String theString) { char aChar; int len = theString
偶然在群里看到这个小题, 就用python做了做. 思路就是建一个够大的列表并初始化,把每个字符的asc码作为下标,存到列表里, 然后该位置的值就存字母的出现次数, 最后再迭代原字符串并判断列表值是否等于1. 输出第一个值为1的字符即可. ps:ord()是把字符串转换为它的asc码. 实现如下: def welcome(p_str): bit_map = [0 for x in range(1000)] temp = p_str for a in temp: bit_map[ord(a)] +
function insertStr(str,tar,n,m){ var x='' var str=str.split('') if(str.length==0) return for(var i=n;i<str.length;i+=m){ str[i]+=tar } x=str.join("") return x } 上述代码中,传入的参数str为要被插入的字符串,tar要插入的字符串,n表示从多少位开始,m表示每隔多少字符插入 var xao="dsdazqdfza
