In computers, variables are stored in memory locations. But the size of the memory location is fixed, so when we try to find the factorial of some greater value like 15! or 20! the factorial value exceeds the memory range and returns wrong results.For calculation of large numbers, we have ...

In mathematics, Greatest Common Divisor (GCD) is the largest possible integer, that divides both of the integers. The condition is that the numbers must be non-zero.We will follow the Euclidean Algorithm to find the GCD of two numbers.Input and OutputInput: Two numbers 51 and 34 Output: The GCD is: 17AlgorithmfindGCD(a, ...

Methods which uses variable arguments (varargs, arguments with three dots) are known as variadic functions.ExampleLive Demopublic class Sample {     void demoMethod(String... args) {       for (String arg: args) {          System.out.println(arg);       }     }    public static void ... Read More

Let's create a MyMap class so that it doesn't hide the actual Map class in JS. We'll create a container object that'll keep track of all our values that we add to the map. We'll also create a display function that prints the map for us. Exampleclass MyMap {    constructor() ... Read More

Now we'll create the put method that'll allow us to put key-value pairs on the dictionary. Now using this we'll implement the put method.Note that JS has objects that act quite like dictionaries. We can just set the container's key property to value. Exampleput(key, value) {    this.container[key] = value; }You ... Read More

We'll implement the get method that searches a given key in the dictionary. Exampleget(key) {    if(this.hasKey(key)) {       return this.container[key];    }    return undefined; }Again, JS objects are very much implemented like dictionaries, hence have most of the functionality we can use directly without any more code ...

We'll implement a clear() function that simply clears the contents of the container. For example,  Exampleclear() {    this.container = {} }You can test this using − Exampleconst myMap = new MyMap(); myMap.put("key1", "value1"); myMap.put("key2", "value2");   myMap.display(); myMap.clear(); myMap.display();OutputThis will give the output −{ key1: 'value1', key2: 'value2' }You can ... Read More

Here we'll implement a for each function in our class and accept a callback that we can call on every key-value pair. Let's see how we can implement such a function − ExampleforEach(callback) {    for (let prop in this.container) {       // Call the callback as: callback(key, value) ... Read More
