Why is this case it is random is there any way to improve it? For teachers to give directions!

CodePudding user response:

Why 1 -- will come? Your vote is certainly more and more, how can I -???

CodePudding user response:

Oh, read the problem is in the wrong and ar_banzhang [I]=1

CodePudding user response:

Not with five run that you define a collection all the generated random number is saved, then define the howling XX howling * * 2, 1 finished 30 cycle, direct statistics in 1, 2, 3, 4, 5 how much is ok

Have considered the feelings of liu?

Find the position of the largest number in an array (subscript) is the Aggregate programming mode, the first records the first subscript results for the initial hypothesis, then loop all the subscript, if a larger Numbers to replace the record,

 var arr=new int [] {1, 5, 2, 3, 8}; 
Var r=Enumerable. Range (0, arr. Length). The Aggregate (new 
{
The subscript=0, 
The maximum=arr [0] 
}, (res, index)=& gt; 
{
Var v=arr [index]; 
If (v & gt; Res. The maximum) 
The return of new 
{
The subscript=index, 
The maximum=v 
}; 
The else 
return res; 
}); 
The Debug. Assert (r. subscript==4);

I found that as long as it is a flat ticket will appear bug, could you tell me if there is a flat ticket, how to deal with to make the system to vote,
