Here is the shortest version (Java 1.5+ required): repeated = new String(new char[n]).replace("\0", s); Where n is the number of times you want to repeat the string and s is the string to repeat. No imports or libraries needed. edited Nov 20, 2015 at 17:55.
#define repeat(n) { for (int i = 0; i < n; i++) #define endrepeat } repeat(10) { //do stuff } endrepeat; [edit] Someone posted a concern about passing a something other than a value, such as an expression. just change to loop to run backwards, causing the expression to be evaluated only once
Debug.WriteLine('-'.Repeat(100)); // For Chars Debug.WriteLine("Hello".Repeat(100)); // For Strings Note that a performance test of using the StringBuilder version for simple characters instead of strings gives you a major performance penality:
Every time I write a while loop where the variable that the condition checks is set inside the loop (so that you have to initialize that variable before the loop, like in your second example), it doesn't feel right. And then I search for python repeat until to remind myself that I should just accept that feeling :) –
Jun 15, 2014 · For base Python 2.7: from itertools import repeat def expandGrid(**kwargs): # Input is a series of lists as named arguments # output is a dictionary defining each combination, preserving names # # lengths of each input list listLens = [len(e) for e in kwargs.itervalues()] # multiply all list lengths together to get total number of combinations nCombos = reduce((lambda x, y: x * y), listLens ...
Feb 5, 2021 · A loop is the best way to achieve this. For example check out this pseudo code: While person is hungry Eat food a bite of food Increase amount of food in stomach If amount of food ate fills stomach person is no longer hungry stop eating food
May 12, 2016 · Put the regEx block in () and add * or +. * 0 to any number of times. + 1 to any number of times. {n} 'n' times. {n,} at-least 'n' times. Non-capturing parentheses group the regex so that you can apply regex operators, but do not capture anything. Eg:
@MikeHarrison ng-repeat is essentially iterating over the object and returning key-value pairs. Think of it like for(var value in arrayOfValues) { ... If you re-assign the variable value inside your loop, you are not changing what is inside of arrayOfValues , you are just re-pointing value to a new object.
How do I repeat the N integers M times each in sequence? I tried nesting seq() and rep() but that didn't quite do what I wanted. I can obviously write a for-loop to do this, but there should be an intrinsic way to do this!
May 17, 2017 · 11. According to MDN, you can just like this: Array.from({length: 10}, () => 5); – Preco Plusb. Dec 25, 2015 at 9:49. 5. @blazkovicz Array (10) creates an array of lenght = 10 without any enumerable properties. .map only works on enumerable properties. The .apply method takes this array, and maps it into an arguments array (an array-like ...
