var arr = [10,20,30]; //计数器思想 var sum = 0; for(var i=0;i<arr.length;i++){ sum += arr[i]; } console.log(sum); var avg = sum/arr.length; console.log(avg);
用js获取一组日期(并把当天算入)中连续的天数 刚开始可能想到单纯的比较日期大小判断连续, 而又有大小月,平闰年这些因素,还是时间戳来的安全; 首先得有一组日期,比如: var arr = [ '2016/02/28', '2016/02/29', '2017/02/26', '2017/02/27', '2017/02/28' ]; //日期格式需要注意,因为考虑到要判断日期的连续性,会把该数组中元素转为时间戳; 然后要加入当前日期,获取: var date = new Date(); var
方法一: Console.WriteLine("请输入三个数字:"); int a = int.Parse(Console.ReadLine()); int b = int.Parse(Console.ReadLine()); int c = int.Parse(Console.ReadLine()); int max; if (a > b) { max = a; } else { max = b; } if (c > max) { Console.WriteLine(c)
private int GetModeNum(List<int> listValue) { List<int> listName = new List<int>(); //众数 List<int> listNum = new List<int>(); //众数的数量 ; foreach (var i in listValue) { ; if (!listName.Contains(i)) { foreach (var j in listValue
