The app.disabled() method checks and returns True if the property name passed is set to False or is disabled. If not, we can disable the property by using the app.disable() method.Syntaxapp.disabled( name )Example 1Create a file with the name "appDisabled.js" and copy the following code snippet. After creating the file, use the command "node appDisabled.js" to run this code as shown in the example below −// app.disabled() Method Demo Example // Importing the express module const express = require('express'); // Initializing the express and port number var app = express(); // Initializing the router from express var ...

Let us understand the concepts of XML Schema Definition (XSD) and Document Type Definition (DTD) before learning the differences between them.XML Schema Definition (XSD)XML is called an Extensible markup language which is used for the representation and manipulation of the data elements. It is a language which is used to communicate the data in the form of structures on the internet.XSD is called as XML scheme definition is the more extended version of the data definition language and is used to explain the structure of the XML schema. The XML features are that it explains the document in a more ... Read More

Suppose we have an array A with n elements and another value d. A farmer has arranged n haybale piles on the firm. The ith pile contains A[i] hay-bales. Every day a cow can choose to move one hay-bale in any pile to an adjacent pile. The cow can do this on a day otherwise do nothing. The cow wants to maximize the hay-bales in first pile in d days. We have to count the maximum number of hay-bales on the first pile.So, if the input is like d = 5; A = [1, 0, 3, 2], then the output ... Read More

Suppose we have a number n. Amal wants to give a name to his pet. He will follow an algorithm. The name will be n characters long. The name will contain uppercase and lowercase letters 'O's and 'o's. The algorithm suggests the i-th letter of the name should be 'O' (uppercase) if i is a member of Fibonacci sequence, and 'o' (lowercase) otherwise. The letters in the name are numbered from 1 to n.So, if the input is like n = 10, then the output will be "OOOoOooOoo", because first fibonacci numbers are 1, 2, 3, 5 and so on.StepsTo ... Read More

Suppose we have an array A with n elements. In a coding contest, in total n students will participate, and before the start, every one of them has some positive rating (integer). A[i] represents the rating of ith student. After the contest ends, every student will end up with some positive integer position. We are expecting the students will take places according to their ratings. If student A has rating strictly lower than student B, A will get strictly greater position than B. We have to find the position at the end of the contest.So, if the input is like ... Read More

Suppose we have an array A with n elements. A has elements either 0 or 1. There is a tree. In consecutive n days, if A[i] is 0 it is not watered, if it is 1 then it is watered, the flower grows in the following manner −If the tree is not watered for consecutive two days, it diesIf the tree is watered on ith day, it grows 1 cmIf the tree is watered on ith and (i+1)th day consecutively, it grows 5 cm instead of 1 cm.If it is not watered on ith day, it will not grow.At the ...

Suppose we have a number n. We want to split it into some non-zero digits whose sum is n. We want to find a solution with minimum possible number of different digits.So, if the input is like n = 13, then the output will be [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]StepsTo solve this, we will follow these steps −for initialize i := 0, when i < n, update (increase i by 1), do:    print 1ExampleLet us see the following implementation to get better understanding −#include using namespace std; void solve(int n){    for (int i = 0; i < n; i++)       printf("1, "); } int main(){    int n = 13;    solve(n); }Input13Output1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,

Suppose we have a number m and a nested list A with n sub-lists. Consider there are m bulbs, initially all are turned off. There are n buttons and each of them is connected to some set of bulbs. So A[i] is the set of bulbs that can be turned on by pressing ith switch. We have to check whether we can lit up all the bulbs or not.So, if the input is like A = [[1, 4], [1, 3, 1], [2]]; m = 4, then the output will be True, because by pressing all switches we can turn on ...

Suppose we have three numbers n, m and z. An office receives calls in every n minutes, and some deliveries come to office in every m minutes. Office is open for z minutes. We have to count the minimum number of orders are collected so there are no pending orders when client calls. Consider taking orders and talking with clients take exactly 1 minutes.So, if the input is like n = 1; m = 2; z = 5, then the output will be 2, because we need to collect orders which comes in second and fourth minutes.StepsTo solve this, we ...

Suppose we have an array A with n elements, and also another number x. We know the lucky numbers are are positive numbers whose decimal representation only contains lucky digits 4 and 7. Form the given n positive integers. We have to count how many of those have not more than k lucky digits?So, if the input is like A = [44, 74, 474, 154]; k = 2, then the output will be 3, because there are three lucky numbers 44, 74 and 474 but 474 has three lucky digits which is more than k. Also 154 has one lucky ... Read More
