java - While Loop won't terminate? -

-

I'm using the loop for a while and when it will not end when it should be if it works correctly When it was done, it ends when randro is either == highbound or == low-end .

The code of the loop: 

  do {do {randno = (int) (Math. (Math.rendum (* * 4)) + 0.5) -1) ; Direction = getDirection (Rendo, Heading); } While (robot. Approach (direction) == iarabot.wall); Println (randno); Println (highbound); Println (lowbound); Println ("---------------"); } While (randonne! = Cumound | randno! = Highbound);

The output is either 3 3 2 ------ , or 2 3 2 ------ , So the loop should end. The first loop ends properly (I try embedding it to work by trying them ...). What's going wrong?

Randonne! = Cummand | Randno! = HighBound is always true, because randno can not be the same as both less and highbound (assuming they are not

So if the loop does not end.

If you want to end, when is different from both the ranges, then your position is lower Change in:

P> 

  while (randno == lessbound || randno == highband)

If you want to end, when rando the same question One of the ranges is to change your position to: 

  while (randano! = Cumoundand randno! = Highband)

Edit: Based on your question, you want the second option.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
