Your first clause in your WHERE is only going to match rows where died is not null. given that, you can reorder the clauses something like: WHERE first_name NOT IN (‘Hannah’, ‘Julia’, ‘Frasier’) AND last_name NOT LIKE ‘%o%’ AND (nationality <> ‘German’ OR speciality <> ‘Photo’) AND ((died – born BETWEEN 50 AND 80 AND … Read more
The issue is here: int [] NumArray; element = NumArray.length -1 Details: you declared NumArray but never initialize it until the constructor is called (this is 100% ok) but the next line you are trying to get NumArray.length of the non initialized array and that is the reason… Solution: place this line inside the constructor, … Read more
The problem is that you input too many characters for cin >> ch;. Since m == 40, you declared it as char ch[40]. This allows you to enter 39 characters (not 40 because of the trailing ‘\0’ character), but you entered much more than that, so it wrote outside the array boundary, which results in … Read more
bThere are several problems in your code. On the fourth line you have int Test = Console.ReadLine(); Console.ReadLine() does not return an int, but a string. string Test = Console.ReadLine(); The name Test is not very descriptive and also violates the convention, that local variables should start with lower-case letter. So we can further improve the line to: string input = … Read more
Interesting puzzle. To get around the need to explicitly pass an argument to f, you can create a class with t (which is type), and use k to create a __new__ method that returns ‘Hello, world!’. Since __new__ is a class method, _ would become the class object when an instance is instantiated: f=t(”,(),{‘__new__’:k(‘Hello, world!’)}) … Read more
Here is how you use Counter(): from collections import Counter count = Counter(a + b + c + d + e) # Add all lists together, and then count them NOTE: You have to convert the inputs into lists first. Here is how you can do that (based on your input – you can change … Read more
For anyone else who’s wondering, I figured it out. You simply have to disconnect the phone from your device first. For example, if it’s plugged into your PC for USB Debugging, simply unplug your phone before closing Android Studio. Or if you’re using Wireless Debugging, disconnect from your phone (or simply turn off Wireless Debugging) … Read more
You can of course use <=. SELECT COUNT(value) FROM primes WHERE value >= 2 AND value <= root; solved Sql Count Query for starting from a value [closed]
YOU WANT TO DO IT LIKE THIS BECAUSE THIS WILL WORK TO SOLVE YOUR PROBLEM. SELECT ‘NetworkKey’ AS AuthKey, COUNT(*) AS TotalCount, SUM(CASE WHEN NetworkSK IS NULL THEN 1 ELSE 0 END) AS NUllcount, SUM(CASE WHEN NetworkSK IS NOT NULL THEN 1 ELSE 0 END) AS NotNullcount FROM EDW.Fact.AuthorizationRequest Happy holidays. 5 solved SQL Query … Read more

Loop through your array and check if the number is within the given range (min number for example is nine and max number is 30). Add it to a newly created array then return the array when you’re done. I’ll provide a code snipit shortly. public ArrayList<Integer> withinRange(int min, int max, int[]array){ ArrayList<Integer> list = … Read more
You could use this library to achieve the results. Material Camera Sample Code for using this lib after integrating the lib, public class MainActivity extends AppCompatActivity { private final static int CAMERA_RQ = 6969; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); new MaterialCamera(this) .start(CAMERA_RQ); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) … Read more
Seems pretty easy. When you search for an element with jQuery, the length property indicates how many elements were found. jQuery(function($) { // run when the document is “ready” if ($(‘#found’).length === 0) { $(‘#hide-me’).hide() } }) 4 solved Hide a div element when other div is not found [closed]
You are comparing the DOM elements (input fields) themselves, not their values. In order to get the values and compare those, you have to actually get the .value property and treat them as Numbers (float or integer or whatever it’s going to be). function submit() { var q = parseFloat(document.getElementById(‘text1’).value); var w = parseFloat(document.getElementById(‘text2’).value); if … Read more
I believe you got the “per kilowatt hour” concept a bit confused. Looks like instead of dividing the “cost per kilowatt hour” by the “kilowatt hours consumed”, you should be multiplying. E.G. basecost = float(cost * kilohour) When I did that, I got what looked to be a nominal bill. craig@Una:~/Python_Programs/Kilowatt$ python3 Killowatt.py Enter watts … Read more
