...50之间,生成一组3个或6个不重复的数组? 如:A1:23 18 41 03 39 2...答:要在一个单元格里面生成一组3个不重复的数组:菜单栏点【工具】【选项】【重新计算】勾选【迭代计算】(最多迭代次数设大一点)确定 A1公式:=IF(LEN(A1)<5,CONCATENATE(INT(RAND()*50+1)," ",INT(RAND()*50+1)," ",INT(RAND()*50+1)),IF((LEFT(REPLACE(A1,1,2,""),LEN(REPLACE...
JS数组5个选3个,5个选2个怎么写答:其他按从小到大顺序)//从3,5,9,6,11里边取3个,有C(5,3)=5*4*3/(3*2*1)=10中取法;//再从剩下的(11-3)=8个数里边取两个,有C(8,2)=8*7/(2*1)=28种取法。//共有10*28=280种排列方式,去掉里边[3,5,9,6,11]的排列(C(5,3)*1=10种),所以最终结果为280-10=...
