What is the primary use of the 'dp' array in dynamic programming?

Step 1: Understand that dynamic programming is a method used to solve complex problems by breaking them down into simpler subproblems.
Step 2: Recognize that many problems can be solved more efficiently if we remember the solutions to these subproblems instead of recalculating them.
Step 3: The 'dp' array is a data structure (like a list or an array) that stores the results of these subproblems.
Step 4: When we need the solution to a subproblem, we first check the 'dp' array to see if we have already calculated it.
Step 5: If the solution is in the 'dp' array, we use it directly, which saves time and effort.
Step 6: If the solution is not in the 'dp' array, we calculate it, store it in the 'dp' array, and then use it.
