你之前回答的问题写的代码为什么我用Mathematica 运行后是全为0呢?我是用5.0的版本还有我不懂你中间 list = RandomSample[{10,10,10,10,10,10,10,10,10,10,5,5,
5,5,5,5,5,5,5,5},10];这句代码的意思

不会吧？会不会是5.0中没有这个语句啊。。 RandomSample[{a},b] 就是返回从数组a中无放回地取出10个元素，返回一个数组，赋值给list

MathematicaFor[k = 0,k < 10,k++,income = 0;For [i = 0 ,i < 1000,i++,list = RandomSample[{10,10,10,10,10,10,10,10,10,10,5,5,5,5,5,5,5,5,5,5},10]; (这个是无重复选取)S = Sum[j,{j,list}];If[S == 50 || S == 100,income -= 100,If[S == 55 || S == 95, int k,s; for(k=s=0;k k^4+2k^2-6k-3=0 2k*3+3k*2+k-1=0 main() {int k=0; while(printf(*)) {k++; if(k 4K方-K-1=0 k等于多少 4k的平方+k-3=0求k, y=x+k/x,当k>0和k |k-1|-k+1=0 k取值范围 k²-k-8=0 求k.求急函数y=(k/x)+b,当k>0,k int k=0;while(k++ k²+2k-2=0 想知道：for(k=0;k k-3k^2+2=0, for{int k=0;k int k=10；while(k=0) k=k+1程序的执行情况 2k³-6k²+6k-3=0 求k值
