Dynamic Memory Allocation

High Level Vs Low Level

In high level language, we don’t need to think about memory allocation. For example, to create dynamic array, we don’t need to initialize the array length. But, all would be different if we move to low level language like C where required strong identifier in variable declaration. Then you face with a problem that required you to check unregistered value on certain array. In higher language, we just need to address new key without need to think about memory allocation. But in low level language, there is no way to do new array key creation as long as we have fixed length array.

Introducing to Dynamic Programming

At the earliest programming level, most people start to solve a problem using brute force algorithm because it’s easy to understand and implemented to any problems. When we move to higher level, the problem become complex and required more memory and time. At this level, we must do optimization. If you have built brute force or greedy algorithm, you may to do optimization by rebuilt your algorithm based on Dynamic Programming method.

What is Optimal Substructure ?

Optimal Substructure is global optimal that constructed from optimal solution of every subproblems. For example, to find the shortest path of graph below; first we need to calculate every sub-path from S to G, then collect any shortest sub-path to create complete shortest path.
