C++ program for length of the longest word in a sentence
Given with the sentence of multiple strings and the task is to find the length of the longest string in the sentence.ExampleInput-: hello I am here Output-: maximum length of a word is: 5 Input-: tutorials point is the best learning platform Output-: maximum length of a word is: 9Approach used in the below program is as follows −Input the string in an array of stringsTraverse the loop till the end of a sentence is not foundTraverse one particular string of a sentence and calculate its length. Store the length in a variablePass the integer values of length of strings ...

Given with an array of integer elements and the task is to multiply the elements of an array and display it.ExampleInput-: arr[]={1, 2, 3, 4, 5, 6, 7} Output-: 1 x 2 x 3 x 4 x 5 x 6 x 7 = 5040 Input-: arr[]={3, 4, 6, 2, 7, 8, 4} Output-: 3 x 4 x 6 x 2 x 7 x 8 x 4 = 32256Approach used in the below program is as follows −Initialize temporary variable to store the final result with 1Start loop from 0 to n where n is the size of an arrayKeep multiplying ...
Read MoreIs it possible to instantiate Type-parameter in Java?
Generics is a concept in Java where you can enable a class, interface and, method, accept all (reference) types as parameters. In other words it is the concept which enables the users to choose the reference type that a method, constructor of a class accepts, dynamically. By defining a class as generic you are making it type-safe i.e. it can act up on any datatype.Exampleclass Student { T age; Student(T age){ this.age = age; } public void display() { System.out.println("Value of age: "+this.age); } } public class GenericsExample { ...

Given with the sequence and the task is to identify whether the given sequence is sa ISBN number or not.What is an ISBN numberISBN stands for International Standard Book Number is a 10 digit number till December 2006 and now it is revised to 13 digit number from 1 January 2007. Given below is the implementation of 10 digits ISBN.ISBN digit has a pattern in it as −Starting 9 digits of a number represents Title, Publisher and Group of the book. The value of first 9 digit can range from 0 - 9Last 1 digit checks whether the ISBN is ...

Read MoreBFS vs DFS for Binary Tree in C++?
BFS (Breadth First Search) − It is a tree traversal algorithm that is also known as Level Order Tree Traversal. In this traversal we will traverse the tree row by row i.e. 1st row, then 2nd row, and so on.DFS (Depth First Search ) − It is a tree traversal algorithm that traverses the structure to its deepest node. There are three most used methods that are used to traverse the tree using DFS. it goes into depth of each node as the root node and then goes to the next one.Solved for a TreeLet’s find the traversal of a ...

Read MoreTribonacci Word in C++
The Tribonacci Word is a sequence of digits. This is similar to the Fibonacci Words. Tribonacci Word is constructed by repeated concatenation of three previous stringsT(n) = T(n - 1) + T(n - 2) + T(n - 3)The first few strings to start, are {1, 12, 1213} So the next one will be 1213 + 12 + 1 = 1213121Algorithmtribonacci_word(n): Begin first := 1, second := 12, third := 1213 print first, second, third for i in range 3 to n, do temp := third third := third + second + ...
Read MoreCheck if a number is Bleak in C++
Here we will see whether a number is Bleak or not. A number is said to be bleak if it cannot be represented as sum of a positive number x and set bit count in x. So x + set_bit_count(x) is not equal to n , for any non-negative number x.The concept is very simple, if the set bit count + the number is not same as the number, then that is Bleak, otherwise it is not.Example#include using namespace std; int set_bit_count(int x) { unsigned int bit_count = 0; while (x != 0) { ...
Read MoreCheck if a number is divisible by all prime divisors of another number in C++
Suppose there are two numbers. We have to check whether a number is divisible by all of the prime factors or the second number or not. Suppose a number is 120. The prime factors are {2, 3, 5}, another number is 75, here the prime factors are {3, 5}. As 120 is divisible by 3 and 5 also, then the decision is yes.If one number is 1, then it has no prime divisors, so answer is True. Otherwise we have to find the GCD of these two numbers. If GCD is 1, then they are co-prime. So answer is false. ...
