[ad_1] You need to learn how to debug your code. If you can’t do that with a debugger, write a function which prints to the screen the relevant information, such as the following: void paxDebug(const char *desc, ll arr[], ll sz, ll n, ll b, ll x, ll pos) { cout << desc << “\n”; … Read more
[ad_1] You can create/open a new file then write in it the concatenation of your variables: $scores_file=”scores.txt”; // open the file $handle = fopen($scores_file, ‘w’) or die(‘Cannot open file: ‘.$scores_file); // create 1rst line and a line feed \n $data=”Number of guesses:”.$_SESSION[‘antal_gaet’].”\n”; // concat the 2nd line $data .= ‘Username:’.$_SESSION[‘username’]; // write to the opened … Read more
[ad_1] You could filter the value after a check, if the lower case value is included in the fields array. var mainArray = [“Title”, “AssignedTo”, “IssueStatus”, “Priority”, “Comment”, “Category”, “RelatedIssues”, “V3Comments”, “TaskDueDate”, “Attachments”], fields = [“title”, “comment”], result = mainArray.filter(a => fields.includes(a.toLowerCase())); console.log(result); ES5 var mainArray = [“Title”, “AssignedTo”, “IssueStatus”, “Priority”, “Comment”, “Category”, “RelatedIssues”, “V3Comments”, … Read more
[ad_1] Statement a[637][i]++ increases the value of the cell 637/i of two-dimensional array a. assert(0) simply aborts program execution at this point (since condition 0 means false, defining that the assertion is never met). Confer this SO answer for a more detailed explanation. [ad_2] solved In c++, what does an increment to a 2D array? … Read more
[ad_1] Your objects initial value: var myObj = [{‘ABC’: ‘5’}, {‘BCD’: ‘1’}] Now if DDD doesn’t exists, just add it: var DDD = “3” var DDDExists = false; myObj.forEach(function(){ if(this.DDD.length > 0){ // If it exists, break the loop DDDExists = true; break; } }) // If DDD doesn’t exists, add it if(DDDExists === false){ … Read more
[ad_1] matches = [] File.readlines(‘data.txt’).each do |line| my_line = line.chomp.split(‘, ‘).map! { |l| l.split(/\s+(?=\d+$)/) }.flatten matches << [[‘player1’, ‘scope_p1’, ‘player2’, ‘score_p2’], my_line].transpose.to_h end p matches Example Here 3 [ad_2] solved Ruby CSV.readline convert to hash
[ad_1] Don’t put the / around the expression. Then you can convert it to a regular expression with new RegExp, and test the password with it. You can loop with .every(), which will perform tests as long as they’re successful. var pwdarray = { “pwd”: [{ “TEXT”: “Password must be at least 6 character(s) long.”, … Read more
[ad_1] Simple and easy-to-understand solution could be as next. The main idea – find index of required type and then retrieve data from this index. Once you’ve find your type you will catch the index and break the loop: $indd = ”; // possible array index with required type value $type = 102; // type … Read more
[ad_1] Please note, the third for loop is nested inside the second loop. So, for each value of j in the other loop body like 0, 1, 2, the inner loop will execute for each time. If you’re bothered that after the first loop, j will be 10, then don’t worry, the statement-1 in the … Read more
[ad_1] An quick fix, using the previous numerically ordered array, could have been: // Save the keys $keys = array_shift($data); /* here, do the sorting … */ // Then apply the keys to your ordered array $data = array_map(function ($item) { global $keys; return array_combine($keys, $item); }, $data); But let’s update my previous function: function … Read more
[ad_1] Sorry but that day I didn’t know about slicing, sorry to bother, here it is: l=[1,2,3,4,5,6,7,8,9];l=[[l[i],l[i+1],l[i+2]] for i in range(0,9,3)];print(L) [ad_2] solved How to print a list as list of list in particular order in Python?

[ad_1] A couple of corrections to your original function ought to do it. var output = {}; // empty object $.each(fruits, function (index, fruit) { var key = fruit.id; // check property exists otherwise initialize it if (!output[key]) output[key] = []; output[key].push(fruit); }); 1 [ad_2] solved How to generate asscoiate array of objects in javascript?
[ad_1] Well, since you want to use String numbers, you will have to wrap them in quotations, but your sorting can be much more readable. I would suggest the following String[] numbers ={“-100”, “50”, “0”, “56.6”, “90”, “0.12”, “.12”, “02.34”, “000.000”}; List<BigDecimal> decimalList = new ArrayList<>(); for(String s: numbers){ decimalList.add(new BigDecimal(s)); } Collections.sort(decimalList); Collections.reverse(decimalList); // … Read more
[ad_1] You could use RegularExpressions for extracting in an easy way each token of your input string. In the following example, support for extra spaces is included also (the \s* in the regular expressions). Remember that always is a great idea to give a class the responsibility of parsing (in this example) rather than taking … Read more
