Given an N-ary tree and we are tasked to find the total number of ways to traverse this tree, for example −For the above tree, our output will be 192.For this problem, we need to have some knowledge about combinatorics. Now in this problem, we simply need to check all ... Read More

To solve a problem in which n − the number of people now each person can either be single or be present in a pair, so we need to find the total number of ways these people can be paired up.Input : 3 Output: 4 Explanation : [ ... Read More

To solve a problem in which we are given an array containing the size of the boxes. Now we are given a condition that we can fit a smaller box inside a bigger box if the bigger box is at least twice the size of the smaller box. Now we ... Read More

Subarrays are the contiguous part of an array. For example, we consider an array [5, 6, 7, 8], then there are ten non-empty subarrays like (5), (6), (7), (8), (5, 6), (6, 7), (7, 8), (5, 6, 7), (6, 7, 8) and (5, 6, 7, 8).In this guide, we will ... Read More

In this article, we will solve the number of subarrays having sum in a given range using the C++ program. We have an array arr[] of positive integers, and a range {L, R} and we have to calculate the total number of subarrays having sum in the given range form ... Read More

If you have ever used C ++, you must know what subarrays are and how useful they are. As we know that, in C++, we can solve multiple mathematical problems easily. So in this article, we will explain the complete information on how we can find M odd numbers with ... Read More

In this article, we will solve the problem of finding the number of subarrays whose maximum and minimum elements are the same using C++. Here is the example for the problem −Input : array = { 2, 3, 6, 6, 2, 4, 4, 4 } Output : 12 Explanation : ... Read More

In this article, we will explain everything about solving the number of subarrays having the sum of the form k^m, m >= 0 in C++. Given an array arr[] and an integer K, we need to find the number of subarrays having sum in the form of K^m where m ... Read More

In this article, we will find out the number of subarrays having a sum less than K using C++. In this problem, we have an array arr[] and an integer K. So now we have to find subarrays that have a sum less than K. Here is the example −Input ... Read More

In this article, we will solve the number of subarrays having sum in a given range using the C++ program. We have an array arr[] of positive integers, and a range {L, R} and we have to calculate the total number of subarrays having sum in the given range form ... Read More
