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”; cout … Read more
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 file … Read more
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”, “TaskDueDate”, … Read more
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).

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

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.”, “EXPRESSION”: … Read more
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 value … Read more
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 second … Read more
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); }, $data); But let’s update my previous function: function mult_usort_assoc(&$arr, … Read more
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) solved How to print a list as list of list in particular order in Python?

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 solved How to generate asscoiate array of objects in javascript?
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); // edit … Read more
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 an … Read more
