[ad_1] Hi use this code. if(a<=21 && b<=21){ return Math.max(a, b); } This is a easy problem, try yourself next time. 1 [ad_2] solved When given a pair of ints, I need my code to be able to return the int that is closest to 21 without going over [closed]
[ad_1] So from the comments: if col is float col[H][W];, your trying to index vx/vy via a float. You would have to cast to int again: int vx2 = vx[static_cast<int>(col[iposy][iposx])]; int vy2 = vy[static_cast<int>(col[iposy][iposx])]; Be careful: There is no implicit index checking, so if your floats are out of range (negative or > WIDTH/HEIGHT), you … Read more
[ad_1] You’re already given the function signature: int largest(), so that’s exactly how you’d write the function (exactly like int main();): // Declares the function int largest(); // Defines the function: int largest() { // The function MUST return an int (or something convertible) otherwise it will not compile return 0; } Or you can … Read more
[ad_1] Your code is duplicating every corresponding list (values) in example1 as many times as the values in example2. Your code is similar to: >>>>two_items = [“A”,”B”] >>>>number = [3] >>>>result = two_items*number[0] [‘A’, ‘B’, ‘A’, ‘B’, ‘A’, ‘B’] To make this clear, it works like string multiplication: >>>>my_string=”Hello ” >>>>print(my_string * number[0]) Hello Hello … Read more
[ad_1] You could use isdigit to check if your string contains digits Example 1 print( all( not c.isdigit() for c in “String doesn’t contain any numbers.” ) ) True Example 2 print( all( not c.isdigit() for c in “String 2 doesn’t contain any numbers.” ) ) False [ad_2] solved How to program to only input … Read more
[ad_1] Let’s look at what happens during the first two iterations. We start with: i = 0 d = 4 L = -5 -4 -3 -2 -1 R = 0 The greater element is L[d], so we add that, change the sign of L[i], and decrement d, so now we have: i = 0 d … Read more
[ad_1] Declare the ed_text and mViewPager in your onCreate like this final EditText ed_text =(EditText)findViewById(R.id.editText1); final ExtendedViewPager mViewPager = (ExtendedViewPager) findViewById(R.id.view_pager); and now you can access the ed_text value in the bt_Goto click listener like this bt_Goto.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(ed_text.getText().toString().length() > 0){ mViewPager.setCurrentItem(Integer.parseInt( ed_text.getText().toString())); } } }); 1 [ad_2] … Read more
[ad_1] Before anything, make your tuple into a list. A list is easier to work with as it is mutable (modifiable), whereas a tuple is not. >>> dates = list((’01/01/2009′, ’02/01/2009′, ’03/01/2009′, ’04/01/2009′)) >>> dates [’01/01/2009′, ’02/01/2009′, ’03/01/2009′, ’04/01/2009′] Request number one, strings of integers: >>> answer1 = [item[:2] for item in dates] # Here … Read more
[ad_1] int x; while(cin>>x) { store the number one by one } //process Simply do it this way. Store the numbers in the array. Or you can do it this way- string s; getline(cin,s); std::stringstream myss; myss<<s; std::string t; int x; std::vector<int> v; while(std::getline(myss,t,’ ‘)) { if(std::stringstream(t)>>x) { // store x in an vector. v.push_back(x); … Read more
[ad_1] you can check it easily with the modulo operator (%), which finds the remainder after the division of one number by another: if(number1 % number2 == 0) { // result of division is integral // or in other words: number1 / number2 = whole number } Note that number1 and number2 have to be … Read more
[ad_1] User Himal say use typeof.. so I can found the answer var myvar=5 alert(typeof myvar); //alerts “number” so to know kind of varible use typeof source : http://www.javascriptkit.com/javatutors/determinevar2.shtml [ad_2] solved How can I identify kind of variable I’m trying to compare in JavaScript?
[ad_1] You can do this var results = numberLists.OrderBy(x => x[0]) .ThenBy(x => x[1]) .ThenBy(x => x[2]); foreach (var result in results) { foreach (var subresult in result) { Console.Write(subresult + ” “); } Console.WriteLine(); } Output 2 3 9 2 4 7 4 7 8 6 8 9 Full Demo here Additional Results Enumerable.OrderBy … Read more
[ad_1] Let’s step through your code. First, you overwrite whatever the high score was with 0: //To save highest score let highscore = 0 let userDefaults = NSUserDefaults.standardUserDefaults() NSUserDefaults.standardUserDefaults().setObject(highscore, forKey: “highscore”) NSUserDefaults.standardUserDefaults().synchronize() Then, you’re checking if “highscore” is in the defaults: if let highscore: AnyObject = userDefaults.valueForKey(“highscore”) { A few notes: This will always be … Read more
[ad_1] First, use split() to split the input into a list. Then, you need to test isnumeric() on every element of the list, not the whole string. Call int() to convert the list elements to integers. Finally, add the sum to counter, not counter_item. my_list = input(“Input your list.(Numbers)\n”).split() while not all(item.isnumeric() for item in … Read more
[ad_1] For asking the user a question, you can use something like printf or puts. To request numbers from the user, scanf is probably the best approach for the level you’re working at. By way of example, here’s a complete program that asks the user for a number then gives them the next number: #include … Read more
