[ad_1] You can’t insert @SuppresWarnings on a return statement. In java 8 you can annotate only classes, methods/constructors, fields, parameters and (new in java 8) local variables.

The count you are referencing on your cout line is from somewhere else. I assume that somewhere in global scope you’re pulling in definitions of two “count” functions and the compiler … Read more
[ad_1] // take an array with some elements $array = array(‘a’,’z’,’c’,’b’); // get the size of array $count = count($array); echo “<pre>”; // Print array elements before sorting print_r($array); for ($i = 0; $i < $count; $i++) { for ($j = $i + 1; $j < $count; $j++) { if ($array[$i] > $array[$j]) { $temp … Read more
[ad_1] for i in range(0,5): password = str(input(“Enter password: “)) password_checker_result = password_checker(password) if not password_checker_result: print(“Invalid password”) else: print(“Valid password”) break This code will work for you, now let me explain: The flow is as following: This is done 5 times (is inside the for loop): 1) Request password from user. 2) Check if … Read more
