Method 1: Think of how you would compute 500! / (20! * 20! * 20! * …) normally. Don’t multiply everything out and divide at the end. Do your divisions in the middle. Then combine this with the modulus reductions from your previous question. Method 2: Prime factorize 500! and 20!. Then subtract out the … Read more
Should be: #include<stdio.h> int main() { int i, j, n; scanf(“%d”,&n); for (i=0;i<=n;i++){ for (j=0;j<=i;j++){ printf(“*”); } printf(“\n”); } return 0; } You forgot to tell scanf you were reading in an integer by using the %d argument 2 solved printing too much stars [closed]
One way is to override the paintComponent(…) method of a JPanel to paint the image using the drawImage(….) method. Another option is use a JLabel with an Icon as the background for the frame. Then you can use the Stretch Icon which will automatically scale based on the space available to the label. This is … Read more
You’re making some conceptual mistakes. You’re confusing JSF with Swing. You’re trying to manipulate the view in the controller. To learn what JSF is, start here. To learn what Swing is, start here. They are not the same. Stop thinking in Swing or searching for Swing solutions when developing with JSF. As to the MVC … Read more
One solution is to use a defaultdict: from collections import defaultdict my_dict = defaultdict(lambda: []) my_dict[‘var1’].append(1) print(my_dict[‘var1’]) # prints ‘[1]’ This would not allow you to simply do print(var1), however, because it would still be undefined in your local (or global) namespace as a tagged value. It would only exist in the defaultdict instance as … Read more
You need for-loop with if/else to run different code for different lists. For list with “PRODUCT NAME PACK” you have to keep list with names in variable – so you may use it in next loops when you get list with numbers For other list you can keep first number as index and rest use … Read more
First of all, you always must include the description of what you have tried so far and what error you encountered while doing so. It is not nice to ask a question directly without showing your efforts in it. Now coming back to your question, it is actually quite very easy, what you can do … Read more
1) You’re missing a closing bracket on the ReactDOM line: ReactDOM.render(<Main />, document.getElementById(‘root’)); 2) You need to call the function for it to work vanilla_JS() In this working example instead of logging to the console I’m returning a string: function Main() { const vanilla_JS = function() { return ‘testing’; } return ( <main> <div>{vanilla_JS()}</div> </main> … Read more
With the slice method you are just extracting a ‘slice’ of the array starting from here (begin) to there (end). To implement the slice function yourself try something like this: function newSlice(array, begin, end) { let tempArray =[]; if(end===undefined || end > array.length) end = array.length; for (let i = begin; i < end; i++) … Read more
It’s better to store sql server connection string in your configuration file (if you are on .net framework then it’s App.Config for desktop apps and Web.Config for web apps) which you can update independently from your compiled app. And then you will be able to connect any sql server you have access to. 0 solved … Read more

Since the strings start with index 0, it is incorrect to iterate through the string using while i <= len(summary):, you should use while i < len(summary): instead. Better yet is to use something like: for i in range(len(summary)): solved problem with comparing string with ‘{‘ sign [duplicate]
You can solve your problem by grouping objects by Id1 and Id2. By the way, you sould share the test model and initialize the collection on problem definition next time ? internal class TestModel { public TestModel(string id1, string id2, string value) { Id1 = id1; Id2 = id2; Value = value; } public string … Read more
You did not specify a type for the parameter of your function. Likely types are int* or char*, but you haven’t given enough information to perfectly deduce the type. bool checkWin(/*You MUST specify a type here!*/ spaceleft) Example: bool checkWin(int* spaceleft) solved How can I check if an element in an array is equal to … Read more
