Clash Royale CLAN TAG #URR8PPP Why is reduce performing better in this use case of finding duplicates in an array [closed] Recent problem stated that given an array of very large size we need to find first duplicate value and return it (not the index but the value). So given an example array of [1,2,3,4,5,3] we need to return 3 since it is the first value with a duplicate in the array. [1,2,3,4,5,3] 3 Now the array in question could be 100K and much larger. Given those requirements there are few solutions that come to mind right away. 1.Using ES6 with Set solution: function firstDuplicate(a) var r = new Set(); for (var e of a) if (r.has(e)) return e; else r.add(e); 2.Using for loop with lastIndexOf: const firstDuplicate = (arr) => for(var i = 0; i < arr.length ; i++) if(arr.lastIndexOf(arr[i]) > i) return arr[i] 3.Using reduce & lastIndexOf: Note: I am aware that this approach mutates the input via splice used to exit from the reduce... splice const...

Cheers Duplicate: stackoverflow.com/questions/107405/… – Daniel Roseman Dec 22 '09 at 21:43 11 Answers 11 You could try to do this with getcode() from urllib getcode() >>> print urllib.urlopen("http://www.stackoverflow.com").getcode() >>> 200 EDIT: For more modern python, i.e. python3 , use: python3 import urllib.request print(urllib.request.urlopen("http://www.stackoverflow.com").getcode()) >>> 200 Following question, using urlopen.getcode does fetch the entire page or not? – OscarRyz Dec 22 '09 at 23:13 urlopen.getcode As far as i know, getcode retreives the status from the response that is sent back – Anthony Forloney Dec 23 '09 at 0:38 getcode @Oscar...

Clash Royale CLAN TAG #URR8PPP How do I invert a matrix in tensorflow-js? Simple question. Is there an operation for it, also, how do you create an identity matrix? I've checked the documentation but can't find a single operation. 2 Answers 2 For now tensorflowJs does not have any direct operator that can return the inverse of a matrix M. You can consider using the module Math.js Having said that, it is possible to invert a matrix using tensorflowJs operators. The following calculates the inverse of a matrix using the adjoint method with tensorflowJs operators. // calculate the determinant of a matrix m function det(m) return tf.tidy(() => const [r, _] = m.shape if (r === 2) const t = m.as1D() const a = t.slice([0], [1]).dataSync()[0] const b = t.slice([1], [1]).dataSync()[0] const c = t.slice([2], [1]).dataSync()[0] const d = t.slice([3], [1]).dataSync()[0] result = a * d - b * c return result else let s = 0; rows = [...Array(r).keys()] for (let i ...

The problem is that I want to display these pictures like a gallery but I can't. I'm doing something like this: for (var x =0; x <= prod.length; x++) require('../../web/image/'+prod[x].picture); Can someone help me? 1 Answer 1 In React and React Native, a component renders using its render function. render For instance, in React Native the native Image component is used for rendering images. To render a single image, your component should include something like this: render() return ( <View> <Image source=require('/react-native/img/favicon.png') /> </View> ); Adding logic inside of your JSX is easy too! Simply wrap any Javascript code inside of curly braces as follows: renderImages() var images = ; for (var x=0; x <= prod...
