Memoization
We have seen that DP is a technique for solving recursive problems more efficiently. Why is this the case? Oftentimes in recursive procedures, we solve subproblems repeatedly. In DP, this does not happen: we memorize the solution of these subproblems so that we do not have to solve them again. This is called memoization.
If the value of a variable at a given step depends on the results of previous calculations, and if the same calculations are repeated over and over, then it is convenient to store the intermediate results so as to avoid repeating computationally expensive calculations.
To better understand the difference between recursion and memoization, let's analyze a simple example: the calculation of the factorial of a number. ...
