**For Loop C++**

### Problem Statement :

A for loop is a programming language statement which allows code to be repeatedly executed. The syntax is for ( <expression_1> ; <expression_2> ; <expression_3> ) <statement> expression_1 is used for intializing variables which are generally used for controlling the terminating flag for the loop. expression_2 is used to check for the terminating condition. If this evaluates to false, then the loop is terminated. expression_3 is generally used to update the flags/variables. A sample loop is for(int i = 0; i < 10; i++) { ... } In this challenge, you will use a for loop to increment a variable through a range. Input Format You will be given two positive integers, a and b ( a <= b), separated by a newline.

### Solution :

` ````
Solution in C :
#include <iostream>
#include <cstdio>
#include <vector>
using namespace std;
int main() {
vector<string> arr;
arr.push_back("zero");
arr.push_back("one");
arr.push_back("two");
arr.push_back("three");
arr.push_back("four");
arr.push_back("five");
arr.push_back("six");
arr.push_back("seven");
arr.push_back("eight");
arr.push_back("nine");
int a, b;
cin >> a >> b;
for(int i = a;i<=b;i++){
if(i > 9){
if(i % 2 == 0) cout << "even" << endl;
else cout << "odd" << endl;
}
else cout << arr[i] << endl;
}
return 0;
}

## Is This a Binary Search Tree?

For the purposes of this challenge, we define a binary tree to be a binary search tree with the following ordering requirements: The data value of every node in a node's left subtree is less than the data value of that node. The data value of every node in a node's right subtree is greater than the data value of that node. Given the root node of a binary tree, can you determine if it's also a

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

View Solution →## Balanced Forest

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

Consider an array of n integers, A = [ a1, a2, . . . . an] . Find and print the total number of (i , j) pairs such that ai * aj <= max(ai, ai+1, . . . aj) where i < j. Input Format The first line contains an integer, n , denoting the number of elements in the array. The second line consists of n space-separated integers describing the respective values of a1, a2 , . . . an .
