Given a rod of length n inches and an array of length m of prices that contains prices of all pieces of size smaller than n. We have to find the maximum value obtainable by cutting up the rod and selling the pieces. For example, if length of the rod is 8 and the values of different pieces are given ...

#include <threads.h> #include <stdio.h> int run(void *arg) { printf("Hello world of C11 threads."); return 0; } int main(int argc, const char *argv[]) { thrd_t thread; int result; thrd_create(&thread, run, NULL); thrd_join(&...

The problem statement is like if we are given two string str1 and str2 then how many minimum number of operations can be performed on the str1 that it gets converted to str2.The Operations can be: Insert Remove Replace For Example Input: str1 = "geek", str2 = "gesek" Ou...

In order to trigger a "upgradeneeded" event you need to request the database with version higher than the current version - otherwise the event won't be triggered. function createTable(dbName, dbversion, tableName) { var request = indexedDB.open(dbName, dbversion); request.onupgrade...

This is a more generic solution applicable in system where the user has option to add indexes to the table that he uses: function createTable(dbName, tableName) { var request = indexedDB.open(dbName); request.onsuccess = function (e){ var database = e.target.result; var version = p...

As it can be seen from the picture above, on a single application we can create: Multiple databases Each database can have multiple object stores (tables) Each object store can have stored multiple objects

Node js code Sample to start this topic is Node.js server communicating with Arduino via serialport. npm install express --save npm install serialport --save Sample app.js: const express = require('express'); const app = express(); var SerialPort = require("serialport"); var po...

Suppose we have this source file that we would like to split: cat -n sourcefile 1 On the Ning Nang Nong 2 Where the Cows go Bong! 3 and the monkeys all say BOO! 4 There's a Nong Nang Ning 5 Where the trees go Ping! 6 And the tea pots jibber jabber joo. 7 On the Nong Ning Nang Comma...

Let's demonstrate the power of PLY with a simple example: this program will take an arithmetic expression as a string input, and attempt to solve it. Open up your favourite editor and copy the following code: from ply import lex import ply.yacc as yacc tokens = ( 'PLUS', 'MINUS', ...

This section explains how the tokenized input from Part 1 is processed - it is done using Context Free Grammars (CFGs). The grammar must be specified, and the tokens are processed according to the grammar. Under the hood, the parser uses an LALR parser. # Yacc example import ply.yacc as yacc ...

Resource dictionaries are accessible only inside the context they were declared, so if we intended to reference resources that are declared in one page context from another page they will not be found. So if we need global resources to be defined like the ones that comes with the framework we do it ...

Almost usually things are a little bit more complex and to support scalability we should split things apart. So we can define various files containing different resources dictionaries, i.e. resources for UI controls' themes, resources for texts and so on, then we merge them all together in App.xaml ...

We now need to access to our declared resources, in order to do that from XAML code we use {ThemeResource ResourceKey} or {StaticResource ResourceKey} to be continued later.

You can add custom post type posts on default wordpress search, Add below code in theme functions.php function my_search_filter($query) { if ( !is_admin() && $query->is_main_query() ) { if ($query->is_search) { $query->set('post_type', array( 'news','post','article' ...

You can use get_results to get multiple rows from database. global $wpdb; $userTable =$wpdb->prefix."users"; $selectUser = $wpdb->get_results("SELECT * FROM $userTable"); This will show all users list in array.

You can get specific file using this function. get_template_part('template-parts/layout'); Include layout.php file from template-parts subdirectory placed in the root of your theme folder.

The goal of backpropagation is to optimize the weights so that the neural network can learn how to correctly map arbitrary inputs to outputs. Each layer has its own set of weights, and these weights must be tuned to be able to accurately predict the right output given input. A high level overview ...

Activation functions also known as transfer function is used to map input nodes to output nodes in certain fashion. They are used to impart non linearity to the output of a neural network layer. Some commonly used functions and their curves are given below: Sigmoid Function The sigmoid is a ...
