Print all the duplicates in the input string in C++
In this problem, we are given a string and we have to find all the characters that are duplicated along with their number of occurrences in the string.Let’s take an example to understand the problem −Input: TutorialsPoint Output: t (3) o (2) i (2)Explanation− The frequencies of occurrence of each character are t → 3; u → 1; o → 2; r → 1; i → 2; a → 1; s → 1; n → 1.Now, to solve this problem we will find the character count and store it in an array from the string. And then print the characters ...

Read MoreHow much should be a JavaScript Line Length?
Try to keep the length of lines less than 80 characters. This would make the code easier to read. Best practice is to move to next line using break if JavaScript statements aren’t fitting in a single line.In addition, move to next line only after a comma or operator. For example, you can add statement like this, with a break after operator,function display() { var a = ""; a = a + isNaN(6234) + ": 6234"; a = a + isNaN(-52.1) + ": -52.1"; a = a + isNaN('') + ": ''"; document.getElementById("test").innerHTML = a; }

Read MorePrint all the pairs that contains the positive and negative values of an element in C++
In this problem, we are given an array of unique integers. And we have to return all pairs of integers(positive and negative integers) that are present in the array.Let’s take an example to understand the problem better −Input: array = {1 , 4 , 7 , -1, 2, 5, -7} Output: -11 -33An easy way to solve the problem is by using two loops and find the positive-negative pairs. But this solution will be a complex one and will have time complexity of the order n2 where n is the size of the array.But, we have to find a more ...
Read MorePrint all the paths from root, with a specified sum in Binary tree in C++
In this problem, we are given a Binary tree and a sum S. And we have to find the path starting from root to any node of the tree, which gives the sum equal to the given sum.InputSum = 14 Output : path : 4 10 4 3 7To find the solution to this problem, we need to find the preorder traversal of the binary tree. And then find the path that adds up to the given sum.Example Live Demo#include using namespace std; struct Node{ int key; struct Node *left, *right; }; Node* insertNode(int key){ Node* temp = ...

Read MorePrint all triplets with given sum in C++
In this problem, we are given an array of unique integers and a sum. And we have to find the triplets which can form the same sum.Let's take an example to solve the problem −Input : array = {0 , 2 , -1 , 1, -2} Sum = 1 Output : 1 2 -2 0 2 -1To solve this problem, we will be finding all the triplets that provide the sum. A simple approach will be using three loops and finding the sum of the elements and return the adequate triplet.Example Live Demo#include using namespace std; void Triplets(int arr[], int ...
Read MoreLinux Package Management with Aptitude
Aptitude is founded by Ncurses for APT front End and debian Bundle Manager, considering the fact that it is text-based and it runs from a terminal or a CLI – command line interface.

It provides the same functionality as the specialized APT tools, like apt-get and apt-cache, but enables options more suitable for interactive use by default.]To get more information about APT, use the following command –$ aptThe sample output ...
Read MorePrint all the sum pairs which occur maximum number of times in C++
In this problem, we are given an array of n unique integers. And we have to find the sum of two integers of the array which has the maximum frequency. The problem has multiple solutions and you need to find them all.Input : array = { 1, 12, 5, 7, 9, 11} Output : 16 12Explanation − sum 16 and 12 occur two times.5 + 11 = 16 & 7 + 9 = 16 1 + 11 = 12 & 5 + 7 = 12Now to solve this problem, our approach to the problem is checking the occurrence every sum ...
