**Input and Output C++**

### Problem Statement :

Objective In this challenge, we practice reading input from stdin and printing output to stdout. In C++, you can read a single whitespace-separated token of input using cin, and print output to stdout using cout. For example, let's say we declare the following variables: string s; int n; and we want to use cin to read the input "High 5" from stdin. We can do this with the following code: cin >> s >> n; This reads the first word ("High") from stdin and saves it as string s , then reads the second word ("5") from stdin and saves it as integer n . If we want to print these values to stdout, separated by a space, we write the following code: cout << s << " " << n << endl; This code prints the contents of string s , a single space (" "), then the integer . We end our line of output with a newline using endl. This results in the following output: High 5 Task Read 3 numbers from stdin and print their sum to stdout. Input Format One line that contains 3 space-separated integers: a , b , and c. Constraints 1 < = a, b, c <= 1000 Output Format Print the sum of the three numbers on a single line.

### Solution :

` ````
Solution in C :
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
int main() {
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
int a,b,c;
cin>>a>>b>>c;
cout<<a+b+c;
return 0;
}
```

## Square-Ten Tree

The square-ten tree decomposition of an array is defined as follows: The lowest () level of the square-ten tree consists of single array elements in their natural order. The level (starting from ) of the square-ten tree consists of subsequent array subsegments of length in their natural order. Thus, the level contains subsegments of length , the level contains subsegments of length , the

Greg has a tree of nodes containing integer data. He wants to insert a node with some non-zero integer value somewhere into the tree. His goal is to be able to cut two edges and have the values of each of the three new trees sum to the same amount. This is called a balanced forest. Being frugal, the data value he inserts should be minimal. Determine the minimal amount that a new node can have to a

Jenny loves experimenting with trees. Her favorite tree has n nodes connected by n - 1 edges, and each edge is ` unit in length. She wants to cut a subtree (i.e., a connected part of the original tree) of radius r from this tree by performing the following two steps: 1. Choose a node, x , from the tree. 2. Cut a subtree consisting of all nodes which are not further than r units from node x .

We consider metric space to be a pair, , where is a set and such that the following conditions hold: where is the distance between points and . Let's define the product of two metric spaces, , to be such that: , where , . So, it follows logically that is also a metric space. We then define squared metric space, , to be the product of a metric space multiplied with itself: . For

View Solution →## Self Balancing Tree

An AVL tree (Georgy Adelson-Velsky and Landis' tree, named after the inventors) is a self-balancing binary search tree. In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property. We define balance factor for each node as : balanceFactor = height(left subtree) - height(righ
