Clockwise Triangular traversal of a Binary Tree
In this problem, we will create a complete binary tree and traverse it in a circular clockwise direction. For the clockwise traversal, we can think of traversing the boundaries of the tree. For example, we can traverse the outer boundary of the tree first. After that, we can remove visited nodes and traverse the inner boundary of the tree. In this way, we need to make min(height/2, width/2) traversal of the given binary tree. Problem Statement We have given a complete binary tree containing N nodes and need to traverse it in a clockwise direction. Sample Examples Input n ...
Read MoreCheck if the Left View of the given tree is sorted or not
In this problem, we will check whether the left view of the binary tree is sorted. The left view of the binary tree means nodes we can see when we look at the binary tree from the left side. In simple terms, we can see only the first node of each level. So, we need to extract the value of the first node and check whether they are sorted to get the output. Problem Statement We have given a binary tree. We need to print whether the binary tree's left view is sorted. If it is sorted, print 'Yes'. ...
Read MoreProgram to convert given Binary to its equivalent ASCII character string
In this problem, we need to convert the binary string to the character string. We can convert the binary string to an ASCII number string first, and then we can convert the character string. Problem statement – We have given a binary string bin_str whose size is multiple of 8. We need to convert the binary string to the character string. Sample examples Input bin_str = "0110110001101010" Output 'lj' Explanation – The ‘01101100’ is equivalent to 108 in the decimal, which is equivalent to the ASCII value of the ‘l’. The ‘01101010’ equals 106, and ...
Read MoreCheck if cells numbered 1 to K in a grid can be connected after removal of atmost one blocked cell
In this problem, we will check whether we can connect all K cells by unblocking any single cell. To solve the problem, we will assume all connected K as a single Island. If any single blocked cell can connect all Island of the matrix, it is only possible to connect all K cells of the matrix. So, If the matrix contains more than 4 Island, it is not possible to connect all cells. Problem Statement We have given a mat[] matrix of size n*m. We have also given a positive integer, K. The matrix contains 0 and -1 in ...
Read MoreMinimum Number of Insertions in given String to Remove Adjacent Duplicates
In this problem, we will count the minimum number of characters we need to insert to remove all adjacent duplicate characters. To solve the problem, we need to count the total number of adjacent duplicate character pairs. Problem statement – We have given a string named str containing N alphabetical characters. We need to find the total number of different characters we require to add to the string such that the resultant string shouldn’t contain any adjacent duplicated characters. Sample examples Input str = "ccddrt" Output 2 Explanation – We need to insert one character ...
Read MoreBoundary Level order traversal of a Binary Tree
In this problem, we will traverse each boundary of the given binary tree in the given order. We will use the recursive approach to traverse each boundary of the binary tree one by one. However, we will also learn the iterative approach using a stack to traverse the binary tree's boundary and increase the code's performance. Problem Statement We have given a binary tree, and we need to traverse each boundary of the tree in the given order. Traverse left boundary in top to bottom manner. Traverse bottom boundary from left to right. Traverse the right boundary from bottom ...
Read MoreCount of simple cycles in an undirected graph having N vertices
Introduction Undirected graphs are an essential component of computer science and graph theory, representing a group of nodes connected by edges without any directionality. One common problem associated with undirected graphs is the counting of simple cycles or circuits, which are closed paths that visit each vertex only once. In this article, we will explore how to get total count of the given undirected graph with N vertices using the powerful programming languages C and C++. Undirected Graph Before we jump into coding, let's ensure everyone grasps what constitutes a simple cycle within an undirected graph. Let us consider an ...
Read MoreDSatur Algorithm for Graph Coloring
Introduction Graph coloring may be an essential issue in graph hypothesis. The DSatur algorithm presents a compelling approach to play down the utilization of colors while performing chart coloring. By deliberately selecting vertices with the most noteworthy immersion degree, DSatur guarantees an optimized color task that maximizes color differing qualities and minimizes color utilization. In this article, we explore the DSatur calculation for chart coloring and its utilization utilizing C++. The calculation decides its title from the two key concepts it utilizes: Degree and Submersion. It considers the degrees of the vertices and their inundation degrees, which speak to the ...
Read MoreLength of Longest increasing sequence of nodes in a given Graph
Introduction In graph hypothesis, the user will understand to find the length of the longest expanding grouping of nodes in a specified graph. It includes deciding the longest way in a chart where each hub within the way features a strictly increasing esteem compared to its past node. In this article, we are going investigate three approaches to unravel this issue utilizing C++. Each approach will be clarified in detail, counting the calculation, step-by-step execution, and yield. To guarantee consistency, we'll utilize the same input for all three approaches, and they will create the same yield. Approach 1: Depth-First Search ...
Read MoreLexicographically smallest string formed by replacing characters according to the given relation
Introduction The task of making the lexicographically smallest string by replacing characters according to a given relation poses a captivating challenge in string control. The objective is to modify the characters inside the input string, following to the required substitution rules, in arrange to get the littlest lexicographic order. In this article, we'll focus on solving this issue utilizing C++. We are going investigate three approaches to handle this issue, each utilizing a one of a kind technique and algorithmic method. These approaches are planned to supply distinctive bits of knowledge into understanding the issue, considering variables such as effectiveness, ...
