How can I find closest date value from an array according to the current date? I want to get the next closest date on this array according to the current date. var dates = [ 'Aug 18, 2018 03:24:00', 'August 19, 2018 03:24:00', 'September 17, 2018 03:24:00', 'September 14, 2018 03:24:00', 'August 18, 2018 03:24:00', 'July 16, 2018 03:24:00', 'July 15, 2018 03:24:00', 'December 15, 2018 03:24:00', 'July 13, 2018 03:24:00', ]; var now = new Date(); 4 Answers 4 First you need to convert each date into a timestamp then subtract each of them by the current date and store the timestamp difference in the temp array then get the index of the minimum value and use the index to access the closest date in the original array. var dates = [ 'July 16, 1995 03:24:00', 'Aug 18, 1995 03:...

remove a character from a data numpy array I am currently importing a .txt file to a numpy array. The .txt file is organized by three columns with hundreds of thousands of rows. Occasionally, for no apparent reason, the third column will have a attached to the number. This causes genfromtxt to import the number as nan . I have tried using a replace function for numpy , but I believe this function is looking for a string because I get an "EOL while scanning string literal" error code.enter image description here numpy genfromtxt nan numpy Any advice? import numpy as np import numpy.core.defchararray as np_f FLR = np.genfromtxt("C:UsersbrandDownloadsPythonMyFilesaupnipam_scan41_3DFLR.txt") FLR = np_f(FLR, '', '') x = FLR[:,][:,0] y = FLR[:,][:,1] z = FLR[:,][:,2] I've added a picture of what the raw data looks like to show what I mean by it having a "" in the data Following is the complete error code I get File "<ipython-...

Intersect between two arrays of objects and keep only matched element and delete the non-matching element based on key of object I have two arrays of objects and I need to intersect between the arrays to find out the common one and delete it from the first array which does not have the same item based on one of the keys. Note that I want to mutate the first array itself. Here is my code sample and what I tried with .map but did not get the expected result. .map (() => { const first = Array.from({ length: 5 }, (_, i) => ({ id: `in-${i}`, name: "one", age: `${i * 5}` })); const second = Array.from({ length: 3 }, (_, i) => ({ id: `in-${i}`, name: "two" })); console.log({ first }); console.log({ second }); const sid = second.map(s => s.id); first.map((f, i) => { if (sid.includes(f.id)) { console.log("✔️ included"); } else { console.log("👎🏻 not included"); first.splice(i, ...

Grouping neighbouring entries with the same value in a 2d array EDIT: I now realized the question was not appropriate for stack but I've gotten a lot of helpful advice anyway. Thanks everyone! I have a 2d array and I want to group together neighbors of the same value. Using C# (working with unity). Let's say I have this: int[,] array { 0,0,0,0,0,0,1,0,0,0, 0,1,1,0,0,0,1,0,0,0, 0,1,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,1,1,1,0, 0,0,0,0,0,0,1,1,1,0 } There are three "clusters" of 1:s. I want to add them to a dictionary with some variable for identification. So maybe first add the neighboring values to a list, add that list to a dictionary, clear the list and move onto the next cluster. The columns and rows would be of equal length in the real thing. I would also want the sorting method to accept arrays of various sizes so no hardcoded values. I parse the array from an XML document. I've tried looking into Array.Sort but the resources I have fou...

Resize array in C# later in the program I am not sure if this is possible in c# but i'm having a variable defined in public partial class Form1 : Form {... ... #region used variables public ulong logP = {0,0,0,0,0,0,0,0} .... .. Then later in the program i want have an option to adjust the size in the program before the main routines will launch over it and do some calculations Because i like to test with vaious sets of numbers and array sizes i would like to have an option to resize the array, for each test (but this array isnt bound to a single procedure, its a global variable that needs to be resizable. As the whole program at various parts is using this array, (under various functions) how should i put this part ulong sumP = new ulong[numericupdown.valeu]; So that it would change this global variable size ? why dont you use a List<ulong> ? – Daniel A.

Why does C support negative array indices? From this post in SO, it is clear that C supports negative indices. Why support such a potential memory violation in a program? Shouldn't the compiler throw a Negative Index warning at least? (am using GCC) Or is this calculation done in runtime? EDIT 1: Can anybody hint at its uses? EDIT 2: for 3.) Using counters of loops in of arrays/pointers indicates Run-time Calculation of Indices. You can legitimately take the address of the Nth element of an array and then negatively index down to -N. – Hot Licks Aug 11 '13 at 14:20 @ 1) : to avoid negative indexing you can use unsigned types as an index, which also has the nice property of failing fast . – wildplasser Aug 11 '13 at 14:29 ...
