mode

问题 I'm currently trying to verify whether or not, given an unsorted array A of length N and an integer k, whether there exists some element that occurs n/k times or more. My thinking for this problem was to compute the mode and then compare this to n/k. However, I don't know how to compute this mode quickly. My final result needs to be n log(k), but I have no idea really on how to do this. The quickest I could find was n k... 回答1: Use a hash table to count the frequency of each value: uint[int]

问题 I am trying to change the clock freq. to 400 kHz (fastmode) but I cant find the file. The problem is, that read(file,buf,1) takes 0.3 ms read(file,buf,count) count > 1 returns the same buf[i] for i < count. It's the buf[0] value I would get if I would use read(file,buf,1). I think that's caused by the sensor as it wants the first bit of SUB to be 1 what the kernel doesnt provide. The oszy. says, f = 88kHz, it shows 18 peaks for one "duration" and the delay between two "durations" is 0.2 to 0

问题 I have written a minor-mode, it defines some key bindings and does some initialization. The mode properly sets up Navi-mode and Navi-mode-map. How do I enhance this minor-mode to change the color of the cursor when Navi-mode is enabled, and change it back whenever the mode is disabled? Can I use the hook Navi-mode-hook? 回答1: Try this: (define-minor-mode foo-mode "doodad" :lighter "" (if foo-mode (setq cursor-type 'bar) (setq cursor-type (default-value 'cursor-type)))) Or, if you anticipate

问题 I'm looking for a mode function in R which I can use for dplyr. The two posts I have seen treats "ties" very differently. This post (Ken Williams) treats ties by selecting the first-appearing value of the set of modes. This post treats ties by noting both values in the same cell. I'm looking a mode function that treat ties as NA AND excludes missing values. I used Gregor's post to treat ties as NA, but I can't seem to exclude the missing values. The variable DF$Color is a character type. Here

问题 I just have a mode from an addon which I want to enable globally. In order to turn on it by hand I need to enter M-x highlight-indentation-mode . So, below is a list of what I have tried yet: (highlight-indentation-mode t) , (highlight-indentation-mode 1) , (setq highlight-indentation-mode t) . Nothing worked. Next I figure out that may be I need to enable a mode globally, and I started google about it. What I have tried next: (define-globalized-minor-mode global-highlight-indentation-mode

问题 I would like to be able to find the most common value given a certain criteria in an adjacent column. For example: >**ROW A** ----- **ROW B** >Blue ---------- Jason >Blue ---------- Jason >Blue ---------- Charles >Red ---------- Alfred >Red ---------- Alfred >Red ---------- Barry >Green --------- Barry I would like a formula that could look like the following if(X=Row_A_Value,Mode of X) For instance if "BLUE" then the output would be "JASON". If "RED" the output would be "ALFRED" I've tried

问题 I finished the code for the Silent Mode Toggle Application (android apps for dummies). My code is identical with the one in the book, with little exceptions because of the newer android. Everything works fine, but if I start the app, it crashes with the error message: Unfortunately, Silent Mode Toggle has stopped. I found out, that the problem is something with the setOnClickListener method. There are no little compile errors, eclipse says everything is cool. The relevant part of the Code:

问题 I've made an application that fills the fields of a webform with data stored in a database. The problem is that when the WebBrowser loads, a JavaScript error pop-up raises and when I try to submit the form it won´t do it because (quote): "An error has occurred ." I have read here that it uses by default IE4: Replacing .NET WebBrowser control with a better browser, like Chrome? And I have tried this, but it didn't work. It looks like it sticks to IE7 no matter what I do: http://blogs.msdn.com

问题 I am creating a simple gradient background by drawing a quad as follows: glMatrixMode GL.GL_PROJECTION glLoadIdentity glMatrixMode GL.GL_MODELVIEW glLoadIdentity ***glPolygonMode GL_FRONT_AND_BACK, GL_LINE*** glDisable glcDepthTest glBegin bmQuads glColor4d 1, 0, 0, 1 glVertex2i -1, -1 glVertex2i 1, -1 glColor4d 0, 0, 1, 1 glVertex2i 1, 1 glVertex2i -1, 1 GL.glEnd GL.glEnable glcDepthTest I then set up my viewing matrices and draw my 3D scene. This works as expected when the polygon mode (of

问题 I've many times done the following: <defs> <filter id="screen"> <feBlend mode="screen" in2="BackgroundImage"/> </filter> </defs> But when I, inside a shape, write "filter="url(#screen)", my shape disappears. I've tried it in every browser (Safari, Chrome, Firefox, FfxNightly). What am I doing wrong? It would help if someone could give me an example that they know works Thanks 回答1: You should try Opera and see the difference. It seems, Opera is the only browser that currently implements this
