[ad_1] strlen( line ) Give the number of characters in line. (Check man strlen.) num_chars += strlen( line ) Add that number to num_chars. strncmp( line, “”, MAX_LINE_LEN ) Compare the contents of line with the empty string (but just to be on the safe side, do not read more than MAX_LINE_LEN characters of line, … Read more
[ad_1] If you’re just asking for a way to parse the variable bits from this kind of text, it’s quite easy: See here: http://tinyurl.com/qjdaj9w var exp = new Regex(@”angle\(Vector\((.*?),(.*?)\),Vector\((.*?),(.*?)\),(.*?),(.*?)\)”); var match = exp.Match(“angle(Vector(JointA,jointB),Vector(JointA,jointB),minValue,maxValue)”); var jointA1 = match.Groups[0]; var jointB1 = match.Groups[1]; var jointA2 = match.Groups[2]; var jointB2 = match.Groups[3]; var max = match.Groups[4]; var min … Read more
[ad_1] It looks to me like the relevant code to the question is this: #dynamicLoadingPanel = render ‘schedules/named_players’ And that somewhere (not in code shown), and update is posted to Availabilities#create, and what is returned is a fresh version of schedules/named_players and dynamically insert that into the page within #dynamicLoadingPanel. Here’s my take: # _schedules/available_players.html.haml … Read more
[ad_1] Do same null-check as you did when invoked action first time: catch (Exception ex) { if (onError != null) onError(ex); return; } If you want to avoid null-checks – attach dummy handler to Action delegate at the top of your method: onError += (e) => {}; 2 [ad_2] solved Can not pass error via … Read more
[ad_1] In Java, unlike in Python, there are no straight-up functions; everything is a method in a class. The closest you can get are static methods, which are associated with the class as a whole and not any particular instance of it. The closest you can get in Java to the Python code you posted … Read more
[ad_1] If you’re using C#: TextBox.Text = string.Format(“({0})”, string.Join(” “, arr)); 0 [ad_2] solved How can i change the int array to string [closed]
[ad_1] No, directly, you can’t. When a function is called from an HTML page, it’s runned by the client’s browser. A modern browser can only run javascript and webassembly. In case you don’t know, webassembly is a low level, assembly like language that your browser can run. Rust projects can be compiled into webassembly and … Read more
[ad_1] The array str, because it doesn’t have an explicit size, is sized to exactly store what it is initialized with. And because an empty string only contains 1 character, namely a terminating null byte, your array is 1 element in size. This means str isn’t large enough to hold any string that’s not an … Read more
[ad_1] The i < 0 and i == 1 lines do not use the dictionary at all. For those early terms, the dictionary lookup would be slower than the calculation anyway. The if (memo.ContainsKey(i)) { return memo[i]; } line also does not set anything new in the dictionary. It reads from the dictionary, but does … Read more
[ad_1] you should aggregate by column and then sum the results, try this: Notice that, the patient name should should have a numerical counter for keeping track. import pandas as pd import datetime import numpy as np # this a dummy set, you should have already this in your data frame dict_df = {‘Patient’: [1,2,3,4,5], … Read more
[ad_1] tl;dr LocalDate.parse( “2022-03-14” ).datesUntil( LocalDate.parse( “2022-04-15” ) ).filter( localDate -> localDate.getDayOfMonth() == 1 ).count() See this code run live at IdeOne.com. 1 Details First, parse the inputs as LocalDate objects. LocalDate start = LocalDate.parse( “2022-03-14” ); LocalDate end = LocalDate.parse( “2022-04-15” ); The LocalDate#datesUntil method creates a stream of LocalDate objects between the two … Read more
[ad_1] you are getting bigger numbers because on this line for(int i=0;i<n;i++){ cin>>arr[n]; } You are changing the value on arr[n] (that doesn’t exist because you array goes from 0 to n-1). Basically you are not changing any value inside the array so its using trash values that were stored on the memory. The fix … Read more
[ad_1] It can be done with a bit of recursion, provided you don’t have too many items in source and also don’t get a combinatorial explosion from how long each sublist is. import java.util.ArrayList; import java.util.List; public class AllCombinations { static void AddCombination(List<List<String>> source, int depth, String prefix, List<String> output) { for (String layer : … Read more
[ad_1] null is one of a few ‘falsy’ values in JavaScript, including NaN, false, 0, “” and undefined. When JavaScript is asked to coerce a value to bool, which if does, the value is checked against falsy values, but is otherwise considered ‘truthy’. Your null was falsy, you used ! to ‘not’ it, making it … Read more
