An integer is called an Armstrong number of order n if it's every digit separate out and cubed and summed up then the sum will be same as the number i.e. abcd... = a3 + b3 + c3 + d3 + ...In case of an Armstrong number of 3 digits, the sum of cubes of each digit is equal to the number itself. For example:153 = 13 + 53 + 33 // 153 is an Armstrong number.Input: Enter two numbers(intervals):999 9999 Output: Armstrong numbers between 999 and 9999 are: 1634 8208 9474Explanation1634 = 13+63+33+43 = 1+216+27+64 = 1634The approach implemented ...

Bogosort simply shuffles a collection randomly until it is sorted. BogoSort is an ineffective algorithm based permutation and combination that's why it is known Permutation sort. BogoSort is very flop sorting technique which is also known as, shotgun sort, stupid sort, monkey sort, or slow sort. The algorithm successively generates permutations of its input until it finds one that is sorted.Input - 53421 Output - 12345ExplanationIn bogosort array will be consist of unsorted element checking if the array elements are in order, and if it is not, then change the position of array elements, by swapping the elements randomly, and ...

Cocktail sort is a variation of bubble sort that is both a stable sorting algorithm and a comparison sort also known as bidirectional bubble sort, cocktail shaker sort, shaker sort (which can also refer to a variant of selection sort), ripple sort, shuffle sort, or shuttle sort. The algorithm differs from a bubble sort in that it sorts in both directions on each pass through the list.Input:53421 Output:12345Explanation In Cocktail, sort array will be consist of the unsorted element. Cocktail sort works in both directions on each pass through the list. It sort array using bubble sorts once forwards and backward.Example#include ... Read More
The HTML DOM small object is associated with HTML element. We can create and access small element using the createElement() and getElementById() method respectively.SyntaxFollowing is the syntax for −Creating a small object −var s= document.createElement("SMALL");ExampleLet us look at an example for the small object − Small object example Create a small element containing some text by clicking the below button CREATE This is normal text function CreateSmall() { var s = document.createElement("SMALL"); var txt = document.createTextNode("This is small text"); s.appendChild(txt); document.body.appendChild(s); } ...

The HTML DOM Input Text readOnly property is used for setting or returning if the input text field is read-only or not. The readOnly property makes the element non-editable but it can still be focused by tab or click. If there is a default value inside a read-only element then it is sent to a server on submit.SyntaxFollowing is the syntax for −Setting the readOnly property −textObject.readOnly = true|falseHere, truly represents the text field is read-only while false represents otherwise. The readOnly property is set to false by default.ExampleLet us look at an example for the Input Text readOnly property ... Read More
The linked list representation of a number is provided in such a way that the all nodes of the linked list are treated as one digit of the number. The node stores the number such that the first element of the linked list holds the most significant digit of the number, and the last element of the linked list holds the least significant bit of the number. For example, the number 202345 is represented in the linked list as (2->0->2->3->4->5).And to add one to this linked list represented number we have to check the value of the least significant bit ...

The HTML DOM Input Text placeholder property is used for setting or returning the placeholder attribute value of an input text field. The placeholder property is used for giving the web page users a hint about the input element by showing a text inside the input field before the user inputs anything. The placeholder text is greyed by default and isn’t submitted to the form unlike the value property.SyntaxFollowing is the syntax for −Setting the placeholder property −textObject.placeholder = textHere, text represents the placeholder text specifying the hint for the user about the text field.ExampleLet us look at an example ...

The HTML DOM Input Text pattern property is used for setting or returning the pattern attribute of an input text field. It checks the text against a regular expression specified by the pattern property.SyntaxFollowing is the syntax for −Setting the pattern property −textObject.pattern = regexpHere, regexp is a regular expression against which the text field is checked.ExampleLet us look at an example for the text pattern property − Input Text pattern property The username can either be of three numeric characters or 6 alphabet characters from a to g USERNAME: GET PATTERN ...

For this problem, to add elements of two given arrays we have some constraints based on which the added value will get changed. the sum of two given arrays a[] & b[] is stored into to third array c[]in such a way that they gave the some of the elements in single digit. and if the number of digits of the sum is greater than 1, then the element of the third array will split into two single-digit elements. For example, if the sum occurs to be 27, the third array with store it as 2, 7.Input: a[] = {1, ... Read More
Permutations, nPr can also be represented as P(n,r) is a mathematical formula to find the number of permutations. The formula of P(n, r) is n! / (n – r)!.The number of permutations on a set of n elements is given by n! where “!” represents factorial.Input:n=5;r=4; Output:120ExplanationP(5, 4) = 5! / (5-4)! => 120 / 1 = 120 5!=1*2*3*4*5*=120Example#include using namespace std; long int fact(int x) { int i, f=1; for(i=2; i
