An algorithm is a group of clearly defined steps used in programming to carry out certain tasks and produce desired results. When we refer to “a set of defined instructions” in this context, we mean that the user is aware of the results of those instructions if they are carried out as intended. Deterministic and ...
People have been referring to computer information that is communicated or stored as “data” since the development of computers. On the other hand, order types also contain data. Data might take the shape of printed numbers or sentences and bytes saved in the memory of electrical devices or knowledge that has been mentally preserved. This ...
Introduction to Coin Change Problem The “coin change problem” expects a solution to find the minimum number of specific denomination coins required to sum up to a given value. This problem can be categorized as a variation of the “knapsack problem”, and the solution can be optimized using the Dynamic Programming approach. So let’s get ...
Problem Statment Consider two matrices X and Y each of the size N*N. We want to calculate the resultant matrix Z which is formed by multiplying the given two matrices i.e, X and Y. Example Let’s consider the below matrices for multiplication. Matrix A has a size N*M and matrix B has a size A*B. ...
Suffix arrays are very powerful data structures in terms of their applications in the field strings and string algorithms like pattern searching, string matching algorithms, the longest common prefix of two strings, counting the number of substrings, and in the field of biology some problems like DNA sequencing which uses suffix arrays to efficiently find the ...
Problem Statement Write a program to delete duplicate nodes present in an unsorted linked list. Print the original linked list, and the linked list obtained after the deletions. Example Consider the following linked list : After you remove duplicates from the linked list : Example Explanation The given unsorted linked list is : There are multiple occurrences ...
Problem Statement An unsorted array nums and an integer sum k is given. Array has non- negative integers in it. Find out the continuous subarray which elements sums up to the given sum. There can be multiple such subarray with given sum, print out the first such subarray with given sum. If the subarray with ...
Problem Statement You are given an array arr[] containing n integers including duplicates. Write a program to find the majority element in an array if it is present. Else print no Majority Element Found. An element is called a majority element when it appears more than n/2 times in an array of length n. Example Input-1 Output-1 Explanation 9 appears 5 times which is ...
Binary Search is an efficient algorithm designed for searching within a sorted list of items. Its approach involves iteratively dividing the search space in half, until the target element found in the array. The time complexity of the Binary Search Algorithm is $O(log_2{n})$, Where n is the size of the sorted linear array. It means ...
A tree represents a hierarchical arrangement of nodes, forming a non-linear data structure. Each node in the tree holds a value and points to its child nodes, creating a branching structure akin to a natural tree. This hierarchical organization facilitates efficient storage and retrieval of data. Types of Trees in Data Structure According to the ...
