golang 中获取字符串个数 在 golang 中不能直接用 len 函数来统计字符串长度,查看了下源码发现字符串是以 UTF-8 为格式存储的,说明 len 函数是取得包含 byte 的个数 // string is the set of all strings of 8-bit bytes, conventionally but not // necessarily representing UTF-8-encoded text. A string may be empty, but //
compared all possibilities with a long test sheet: 0,140625 sec for lastrow = calcws.Cells.Find("*", [A1], , , xlByColumns, xlPrevious).row 0 sec for iLastRow = calcws.Cells(rows.count, "a").End(xlUp).row and numofrows = calcws.Cells.S
List<Integer> list 为不重复的数字集合,例如:1,2,3,4,5,6,7,8,9,10 从中随机获取不重复的6个数.代码如下. List<Integer> list = new ArrayList<Integer>(); for(int i=0;i<30;i++){ list.add(i); } for(int i = 0;i<6;i++){ //显示数字并将其从列表中删除,从而实现不重复. System.out.println(list.
