Kirat range range(stop) range(start, stop[, step]) >>> for n in range(17, 100, 10): print n 17 27 37 47 57 67 77 87 97 solved Writing a loop with a step size 10, to print out all 2-digit numbers ending in 7 in increasing order in python
~$ echo one && echo two This runs the 2. command only if the first command succeeds. ~$ echo one ; echo two This always runs the 2. command. ~$ echo one || echo two This runs the 2. command only if the first command fails. A command is considered successful if its exit code … Read more
Use else if. $a = 1; if($a === 1) { // do something } else if ($a === 2) { // do something else } Note that in most case the switch statement is better for that, like: switch($a) { case 1: // do something break; case 2: // do something else break; } or: … Read more
You can try this: str = str.replace(/\w*\(\d*\)/g, function () {return ‘(‘ + arguments[0] + ‘)’;}); A live demo at jsFiddle EDIT Since you’ve changed the conditions, the task can’t be done by Regular Expressions. I’ve put an example, how you can do this, at jsFiddle. As a side effect, this snippet also detects possible odd … Read more
Only one of your constructors allocates memory for width and height. The other one has undefined behaviour. 1 solved constructor overloading. Getting the wrong solution [closed]
I tried to run that and my outputs for r1 and r2 are qwdaweqwe asdas–sd (two spaces) and basically it is what the code should be doing. But if I get your intention right, you want to work with those empty strings. Then you should be feeding your function with different numbers, because array indexing … Read more
You should not reprint all the map for each cycle. The better way is to use Console.SetCursorPosition method and rewrite just modified symbols: foreach(var changedSymbol in changes) { Console.SetCursorPosition(changedSymbol.Row, changedSymbol.Column) Console.Write(changedSymbol.Value); } 1 solved How to make small changes for console output without repeating all unchanged values
You can sorted both DataFrames – columns c_x and c_y, for movies is used DataFrame.pivot, count non missing values by DataFrame.count and append to df1: df2[[‘c_x’,’c_y’]] = np.sort(df2[[‘c_x’,’c_y’]], axis=1) df2[‘g’] = df2.groupby([‘c_x’,’c_y’]).cumcount().add(1) df2 = df2.pivot(index=[‘c_x’,’c_y’], columns=”g”, values=”movie”).add_prefix(‘movie’) df2[‘number’] = df2.count(axis=1) print (df2) g movie1 movie2 number c_x c_y bob dan c f 2 uni a … Read more
scanf doesn’t print that string, that’s just used to check the format of the input. Try: printf(“Input N value: “); scanf(“%d”, &N); solved Hadamard matrix code
myDictionary appears to be a Dictionary<string, string> type. Seeing as you store “Pokemon Name:” and “name” just fine one line above. As such, you can just call hp.ToString() to store it. Make sure to once again convert it back to int when using it though. Alternatively, you can make a Dictionary<string, object> storage to keep … Read more
I would just directly match the ID = num expressions: Find: \bID = (\d+)\b Replace: ID=$1 Demo Note that if you are not sure whether there would be whitespace on both sides of the = sign, you could use \bID\s*=\s*(\d+)\b. However, this would match every ID line, even those which are already in the correct … Read more
The “best” way (in my opinion) to prevent “spaghetti” style is to differentiate php and html like: <?php while($row = mysqli_fetch_array($result){ ?> <div class=”imagem”> <img src=”<?php echo $row[‘logo’];?>” width=”180px”> </div> <?php } Side note: Next time if your question have a code use the tools <> (html/js) or {} (php and others lang) 1 solved … Read more
The bison file (or at least, a version of it) is in the css directory as CSSGrammar.y.in. That file is preprocessed and then run through bison using a perl script. Apparently the flex scanner was rewritten in 2011/12; see this webkit bug. The handbuilt scanner is part of CSSParser.cpp. By looking back in the git … Read more
You should separate setting the display property from setting the properties involved in the animation. If you set them in one round the animations won’t run (the problem is with display: none). One way is to do a setTimeout. Also, my suggestion is to never change style properties from JS, always manipulate classes for better … Read more
You answered your own question by reading the documentation. What if the item is not in the tree, or has already been removed, will this method raise an exception? And then the documentation: Returns true if this set contained the element So it will return false if the set does not contain the element (“not … Read more
