range

问题 I have an initial and a final date range = 1/1/2015 - 1/30/2015 I have these date ranges that represent dates of unavailability. 1/5/2015 - 1/10/2015 1/15/2015 - 1/20/2015 1/22/2015 - 1/28/2015 I want this output, mainly the dates of availability from the main range: A: 1/1/2015 - 1/4/2015 B: 1/11/2015 - 1/14/2015 C: 1/21/2015 - 1/21/2015 D: 1/29/2015 - 1/30/2015 I tried to generate a sequential date range like this in order to get the exception dates with Except() but I think I'm

问题 the topic pretty much describes what we would like to accomplish. a) start with a possible range of integers, for example, 1 to 10000. b) take any md5 hash, run it thru this algo. c) result that pops out will be an integer between 1 to 10000. we are open to using another hashing method too. the flow would ideally look like this: string -> md5(string) -> algo(md5(string),range) -> resulting integer within range is something like this possible? final note: the range will always start with 1. if

问题 I'm trying to accomplish the following in C#/.NET 2.0: Given an IPAddress object (say, 192.168.127.100) and another IPAddress object containing the IPv4Mask / subnet mask (say, 255.255.248.0), I should be able calculate the start and end of the IP Address range. (Yes, I'm trying to do a for-loop thru a range of addresses on a subnet.) Theoretically, I should be able to bitwise AND on the IPAddress and the SubnetMask to get the IPStart. Then I should be able to perform a bitwise XOR on the

问题 I have numerical data in a vector< vector < double> > and need to add scalar values to them as follows: vector <vector<double> > data ( M, vector<double>(N) ); vector <double>scalars(N); data[0][0] += scalars[0]; data[0][1] += scalars[1]; ... data[0][N-1] += scalars[N-1]; data[1][0] += scalars[0]; data[1][1] += scalars[1]; ... data[1][N-1] += scalars[N-1]; ... data[M-1][N-1] += scalars[N-1]; Of course this is possible with two for loops. I was wondering if it can be done as simply with

问题 I have this site http://talkwithstranger.com/ I am running it on socket.io and run it via forever js. Forever logs shows the following errors. Can any Node JS expert help me fix these?

问题 I have a list of marked individuals (column Mark) which have been captured various years (column Year) within a range of the river (LocStart and LocEnd). Location on the river is in meters. I would like to know if a marked individual has used overlapping range between years i.e. if the individual has gone to the same segment of the river from year to year. Here is an example of the original data set: ID Mark Year LocStart LocEnd 1 1081 1992 21,729 22,229 2 1081 1992 21,203 21,703 3 1081 2005

问题 I am trying to collapse a series of intervals into fewer, equally meaningful intervals. Consider for example this list of intervals Intervals = list( c(23,34), c(45,48), c(31,35), c(7,16), c(5,9), c(56,57), c(55,58) ) Because the intervals overlap, the same intervals can be described with few vectors. Plotting these intervals make obvious that a list of 4 vectors would be enough plot(1,1,type="n",xlim=range(unlist(Intervals)),ylim=c(0.9,1.1)) segments( x0=sapply(Intervals,"[",1), x1=sapply

问题 Summary: Unable to cache and use the cached audio via a Service Worker. Trying to: cache relatively small audio files (2-3mb) using service worker and cache API. These are loaded/played via a HTML Audio element, which usually sets a 'range' header. Problem: Service worker responds with the whole content, ignoring the range header, and the Audio element ignores the content and does not play. Without service worker: server obeys the range header, sends partial content, Audio element is happy

问题 I have 2 dataframes: > access V1 V2 V3 1 chr10 136122 136533 2 chr10 179432 179769 3 chr10 182988 183371 4 chr10 224234 224489 5 chr10 237693 237958 and > peaks V1 V2 V3 1 chr10 126122 126533 2 chr10 179450 179730 3 chr10 182788 183350 4 chr10 224244 224500 5 chr10 237695 237950 The coloumn V2 and V3 are start and end of regions (range) in both dataframes. I want to keep those rows in peaks dataframe for which access$V1 == peaks$V1 AND which fall in the range (or regions) of access dataframe.

问题 I am building a small vba script that is merging tables from several workbook into one single worksheet of another workbook. The error is raised when I try to set the destination range's value: wksPivotData.Range(wksPivotData.Cells(CurrentRow, 1)).Resize(tbl.ListRows.Count, tbl.ListColumns.Count).Value = _ tbl.Range.Value The error: "Run-time error '1004': Application-Defined or object-defined error" I went through similar questions, and the general answer is what I found in this one: The
