Questions & Step-by-Step Solutions

In dynamic programming, what is the purpose of the 'table'?
  • Step 1: Understand that dynamic programming is a method used to solve problems by breaking them down into simpler subproblems.
  • Step 2: Recognize that some subproblems may be solved multiple times during the process.
  • Step 3: The 'table' is a data structure (like an array or a matrix) used to keep track of the results of these subproblems.
  • Step 4: When a subproblem is solved, its result is stored in the 'table'.
  • Step 5: If the same subproblem needs to be solved again, the algorithm can simply look up the result in the 'table' instead of recalculating it.
  • Step 6: This saves time and makes the algorithm more efficient.
