mode

问题 The question goes: Write a method called mode that returns the most frequently occurring element of an array of integers. Assume that the array has at least one element and that every element in the array has a value between 0 and 100 inclusive. Break ties by choosing the lower value. For example, if the array passed contains the values {27, 15, 15, 11, 27}, your method should return 15. (Hint: You may wish to look at the Tally program from earlier in this chapter to get an idea of how to

问题 I have a 2D array containing integers (both positive or negative). Each row represents the values over time for a particular spatial site, whereas each column represents values for various spatial sites for a given time. So if the array is like: 1 3 4 2 2 7 5 2 2 1 4 1 3 3 2 2 1 1 The result should be 1 3 2 2 2 1 Note that when there are multiple values for mode, any one (selected randomly) may be set as mode. I can iterate over the columns finding mode one at a time but I was hoping numpy

问题 I'm summarizing data in a data.table, group by, where I need to take a single value of a variable in a group. I want this value to be the mode of the group. I think it needs to be mode because usually a group is 8 rows and it will have 2 rows at one value and the other 6 or so rows will be another value. Here's a simplified example, from this: key1 2 key1 2 key1 2 key1 8 key1 2 key1 2 key1 2 key1 8 I want this: key1 2 I was having trouble using the standard mode function provided by base R,

问题 I have made a Kiosk-mode app that works well after install (is based on Activity.startLockTask()). After re-booting the device (a Nexus 5X running Android 8.1), I cannot use the app because the keyboard cannot be made to appear on screen. I give the command to reboot while the app is active (in full screen and set as device launcher) in order to test if it remains in Kiosk mode after restart. Result is that it remains in Kiosk mode, but the soft keyboard cannot be activated by the user. Any

问题 Is there a way to start different emacs mode using command line? For example, is it possible to run emacs as follows? emacs --org-mode # to start orgmode emacs --python-mode # to start python mode I can just run emacs to input 'M-x org-mode' thereafter, but I wonder if I can start different modes. 回答1: You can call functions with the -f argument, so to start org-mode use: emacs -f org-mode 来源： https://stackoverflow.com/questions/4879365/how-can-i-start-different-mode-with-emacs-in-command

问题 so I saw this on a random website from awwwards ( https://mallardandclaret.com/about/ ) I was wondering how can this be achieved. I've got this codepen: https://codepen.io/anon/pen/REBYdM#anon-signup and well, I tried using mix-blend-mode:multiply; but it's obviously not the same. I'm looking for a bigger difference in terms of colors ( maybe inverse them, or something ). Can anyone help me with this one? Much appreciated :). edit: so they are using this one: mix-blend-mode: exclusion; but in

问题 I am trying to use a ToggleButton to switch AirPlane mode on and off. I am not sure how to go about this. My permissions are: <uses-permission android:name="android.permission.WRITE_SETTINGS"/> <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/> My .XML file looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout

问题 I would like to turn off the airplane mode if num>50, I implemented this code (from Toggle airplane mode in Android) but when executed I get a force close, can any one help here? if(num>50){ // read the airplane mode setting boolean isEnabled = Settings.System.getInt( getContentResolver(), Settings.System.AIRPLANE_MODE_ON, 0) == 1; // toggle airplane mode Settings.System.putInt( getContentResolver(), Settings.System.AIRPLANE_MODE_ON, isEnabled ? 0 : 1); // Post an intent to reload Intent

问题 I have a large data set with 11 columns and 100000 rows (for example) in which i have values 1,2,3,4. Where 4 is a missing value. What i need is to compute the Mode. I am using following data and function ac<-matrix(c("4","4","4","4","4","4","4","3","3","4","4"), nrow=1, ncol=11) m<-as.matrix(apply(ac, 1, Mode)) if i use the above command then it will give me "4" as the Mode, which i do not need. I want that the Mode will omit 4 and display "3" as Mode, because 4 is a missing value. Thanks in
