[ad_1] You could just create a function with a return value instead.. #include <iostream> #include <optional> #include <string> using namespace std; void myFunction(optional<string> name = nullopt) { if (name == nullopt) { cout << “I wish I knew your name!” << endl; } else { cout << “Hello ” << name.value() << “!” << endl; … Read more
[ad_1] I suspect you are trying to achieve this by using one a single join between the tables – whereas what you actually need is two separate joins: SELECT table1.module as mod_code, table1.season as psl_code, table2.Sdate as ypd_sdate, table3.Edate as ypd_edate FROM t1 as table1 JOIN t2 as table2 ON table2.yr = table1.year AND table2.season … Read more
[ad_1] A one possible solution is to define a custom predicate like this: Predicate<Item> myPredicate = item -> randomVar == 42; Then you can use the predicate in your stream: items .stream() .filter(myPredicate) .forEach(System.out::println); [ad_2] solved Filtering on unrelated variable in java streams
[ad_1] Left join input list to the target table/column and keep rows having NULL in the fields from the “words” table. WITH query_input(word) AS ( VALUES (‘word 1’), (‘word 2’), (‘word 0’), (‘word 3’), (‘word 5’) ), — Remove this CTE when querying against your db. dict(id, word, definition) AS ( VALUES (1, ‘word 1’, … Read more

[ad_1] Here if you have defined i<=user.length that means i<=5 since you array length is 5 but when you are indexing the array to print it can print between 0 to 4 indexes when it reaches index 5 there is no value in the array for index 5 hence it throws index out of bound … Read more

[ad_1] In python, tuples are defined with tup = (val1,val2,…). This is what you’re doing when you define wholeAssDocumentation. Since tuples don’t have a re method, you’re getting that error. Other than that, I suggest you read the regex documentation because that’s not how you use a regex on a string either. Also you’re overwriting … Read more

[ad_1] I figured it out by replacing keyCode with charCode and changing the event to keypress. editor.on(“keypress”, function (cm, event) { if (!cm.state.completionActive && event.charCode != 13 && event.charCode != 123) { CodeMirror.commands.autocomplete(cm, null, {completeSingle: false}); } }); [ad_2] solved What is the keycode for the open curly brace {
