Greedy Method is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most immediate benefit. It is called "greedy" because it makes a series of choices that seem the best at the moment, without considering the global picture. This approach is often used for optimization problems, where the goal is to find the best solution from a feasible set of solutions.

The Greedy Method is characterized by its simplicity and efficiency. It typically operates in a single pass through the input data, making decisions based on local optimality. This makes it well-suited for problems where a global optimum can be reached by selecting local optima.

However, the Greedy Method does not always yield an optimal solution. It relies on the problem having the property of optimal substructure, meaning that a globally optimal solution can be arrived at by choosing a locally optimal solution. If this property does not hold, the Greedy Method may produce a suboptimal solution.

Examples of problems that can be effectively solved using the Greedy Method include the Activity Selection Problem, the Fractional Knapsack Problem, and the Huffman Coding algorithm. In each of these cases, the Greedy Method provides a straightforward and efficient approach to finding a solution.
