                  Facebook is the dream company of almost every software engineer. If you are doing interview preparation, you can't skip the must do coding questions for Facebook. Facebook is the product-based company and tests the candidate on data structures and algorithms, and logical questions. The coding level is a bit tough, but you can do it with your hard work. Below is the list of coding questions you must prepare before sitting for Facebook. Smallest string which not a subsequence of the given string Maximum length possible by cutting N given woods into at least K pieces Count possible decodings of a given Digit Sequence | Set 2 Find the maximum path sum in a binary tree   Maximize profit for buying and selling stock given a series of price vectors Given  m  sorted arrays, find the  k- th smallest value Binary search in a sorted, rotated array Given a string, check if it is a palindrome  by ignoring spaces. E.g. race car would be a palindrome. Given two very large string

  Discuss in detail what happens when you write a code and compile it. What is multithreading? State any C++ multithreading framework you might have worked with. Explain encapsulation, abstraction, polymorphism. Explain inheritance. What is the Diamond problem? How memory is allocated in C++. What is malloc? Differences from calloc? What is a microprocessor? Explain microservices architecture. Explain normalization and all their forms. Differences between inner and outer joins. DFS vs. BFS What is the heap? Detect a loop in the linked list. If a loop exists, return the start node of the loop. Find the third most frequent element in an array. Finding n next permutations using some specific set of digits given.   Find the number of ways of reaching from top left to bottom right of a matrix.   Minimum number of jumps to reach end given a number N. print in how many ways it can be represented as N = a+b+c+d , 1< =a< =b< =c< = d; 1<=N< = 5000  given two number l and r (l&l

In this Article, we will we building a pokemon app using pokemon api. I hope you have Flutter installed and somewhat familiar with Flutter and APIs. Calling APIs for the data and then displaying that extracted data as a beautiful UI is my favorite task. Let's have a look what we will be building today -  1. Add "http" dependency in pubspec.yaml 2. Add this code in main.dart -  import 'package:http/http.dart' as http; import 'dart:convert' ; import 'package:flutter/material.dart'; void main () { runApp ( MyApp ()); } class MyApp extends StatelessWidget { @override Widget build ( BuildContext context) { return MaterialApp ( debugShowCheckedModeBanner : false , home : MyHomePage (), ); } } class MyHomePage extends StatefulWidget { @override _MyHomePageState createState () => _MyHomePageState (); } class _MyHomePageState extends State < MyHomePage > { Map pokeData; List pokeLis
