A greedy algorithm is similar to a dynamic programming algorithm, but the difference is that solutions to the subproblems do not have to be known at each stage; instead a "greedy" choice can be made of what looks best for the moment.
Consider this example.
You are standing at a place A. You are to goto B. There are intermediate places C1,C2 ...
You want to minimize distance travelled.
Greedy Method of Solving
You don’t want to try all intermediate places. You go to the nearest intermediate place. Why? You feel by going to the nearest intermediate place, you will minimize the distance to B.
