WebIt can be used to solve problems such as scheduling, Huffman coding, and finding the shortest path in a graph. Overall, the Greedy algorithm is a useful approach for solving optimization problems, but it should be used with caution, as it may not always lead to the best global solution.

Webrooms used in the greedy solution –Let k be the number of rooms the greedy algorithm uses and let R be any valid schedule of rooms. There exists a t such that at all time, k events are happening simultaneously. So R uses at least k rooms. So, R uses at least as many rooms as the greedy solution. Therefore, the greedy solution is optimal.
