Read MoreDescription of logic controller interface
We use a logic controller and it is used in industry for the process of control done by the software. Multiple inputs are typically accepted which performs a total complete sequence of operations carried out both arithmetic and logically. The outputs generated are used for the maintenance of the process within the specified desired limits. Visual display is provided by the state of process at any instant of time. The logic controller which interfaces and thus provides a buffered output of 12 lines and which is fed to the buffer inputs of 12 lines only specified for the user. The ...
Read MoreHow to use size() in android LinkedBlockingDeque?
Before getting into the example, we should know what LinkedBlockingDeque is. It is implemented by Collection interface and the AbstractQueue class. It provides optional boundaries based on linked nodes. It going to pass memory size to a constructor and helps to provide memory wastage in android.This example demonstrates about How to use size() in android LinkedBlockingDequeStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml.

Read MoreC++ program to Check if a Given Binary Tree is an AVL Tree or Not
AVL tree is a self-balancing Binary Search Tree where the difference between heights of left and right subtrees cannot be more than one for all nodes.This is a C++ program to check if a given Binary Tree is an AVL Tree or not.AlgorithmBegin function AVL() returns true if the given tree is AVL otherwise false. if(root == NULL) return 1 leftheight = height(root->left) rightheight = height(root->right) if(abs(leftheight-rightheight) left) && AVL(root->right)) return 1 return 0 EndExample#include using namespace std; class nod { //node declaration public: int data; ...
Read MoreDecimal counter using logic controller
We write a program in the 8085 which is written in assembly language just for the implementation of a decimal counter which is used by the logic controller interface. The input of the starting count must be the input through the complete interface and moreover we display the count on the interface.Let us consider a sample program on this –The program which follows it should always contain an infinite loop until the inputs of the user contains a valid value of two-digit Binary Coded Decimal value just only to the Port B. After that the initial count gets displayed by ...
