根据java代码改写成js,下边js文件代码: function StringBuffer() { this.__strings__ = []; }; StringBuffer.prototype.append = function (str) { this.__strings__.push(str); return this; }; //格式化字符串 StringBuffer.prototype.appendFormat = function (str) { for (var i = 1; i
曼-惠特尼U检验(Mann-Whitney检验) How the Mann-Whitney test works Mann-Whitney检验又叫做秩和检验,是比较没有配对的两个独立样本的非参数检验.思想是这样的:假定要检验两组数据之间有没有差异.首先,不管分组把所有数据排序.按照数值大小给定一个值叫做秩.最小的值秩为1,最大的为N(假定两个样本总共有N个观察值).如果有相同的值,就得到相同的秩.相同的值的秩是他们的秩的平均值.如果两组的秩的和差距比较大,就会得出较小的p值,认为这两组间有显著差
JS分割字符串并放入数组的函数: var InterestKeywordListString = $("#userInterestKeywordLabel").html(); var InterestKeywordListArr = []; var t = ''; for (var i = 0; i < InterestKeywordListString.length; i++) { var tmp = InterestKeywordListString.charAt(i);
We have two special characters. The first character can be represented by one bit 0. The second character can be represented by two bits (10 or 11). Now given a string represented by several bits. Return whether the last character must be a one-bit c
如下代码段是关于C#返回字符串的字节长度,一个中文算两个字符的代码. public static int GetLength(string str) { if (str.Length == 0) return 0; ASCIIEncoding ascii = new ASCIIEncoding(); int tempLen = 0; byte[] s = ascii.GetBytes(str); for (int i = 0; i < s.Length; i++) { if ((int)s[i]
