In the context of dynamic programming, what does 'overlapping subproblems' mean?
Subproblems that can be solved independently
Subproblems that are solved multiple times
Subproblems that do not share any common elements
Subproblems that are always unique
Overlapping subproblems refer to the situation where the same subproblems are solved multiple times in the process of solving a larger problem.

Q: In the context of dynamic programming, what does 'overlapping subproblems' mean?
Solution: Overlapping subproblems refer to the situation where the same subproblems are solved multiple times in the process of solving a larger problem.
Steps: 4
Step 1: Understand that a problem can often be broken down into smaller parts called subproblems.
Step 2: Recognize that in some cases, the same subproblems appear multiple times when solving the larger problem.
Step 3: Realize that solving the same subproblem again and again is inefficient.
Step 4: Learn that dynamic programming helps by storing the results of subproblems so they can be reused, avoiding repeated calculations.
