Find In Mountain Array
A mountain array is defined as an array that increases to a peak element and then decreases. You need to find the target element target in the mountain array and…
1.1) Dynamic Programming Explained
Dynamic Programming is a problem-solving technique used to solve complex problems by breaking them down into smaller overlapping subproblems and solving each subproblem only once, storing its solution for future…
1.1) Greedy Algorithms
Greedy algorithms are problem-solving techniques that make locally optimal choices at each step with the hope of finding a global optimum (best overall solution). At each decision point, a greedy…
1.1) What is Backtracking?
Backtracking is a problem-solving technique that involves exploring all possible solutions to find the correct one. It is often used when dealing with problems that have multiple potential solutions, and…
1.1) What is Recursion?
Recursion is a programming concept where a function calls itself to solve a problem in smaller subproblems. In simple terms, it's like solving a big problem by breaking it down…
Sorting Algorithms: Introduction
They are algorithms designed to arrange a list of items in a specific order, such as ascending or descending numerical order or lexicographic order for strings. Sorting is a fundamental…
Searching Algorithms
Searching algorithms are algorithms designed to find the location or existence of a specific item (also known as a target or key) within a collection of data, such as an…
What is Graph data structure?
A graph is a collection of nodes (vertices) and edges (connections) that represent pairwise relationships between nodes. Graphs are widely used to model various real-world systems, including social networks, transportation…
