GFG Minimum Cost for N Characters | Recursion to DP | C++

GFG POTD - Minimum Cost for N Characters In this video, we solve Minimum Cost for N Characters using Recursion and Dynamic Programming. We start with the recursive solution and then optimize it using Memoization. Approach: • Recursion • Memoization • Copy and Delete operations • Even and Odd cases • Detailed dry run • DP optimization Key Idea: To generate N characters, we can either add one character at a time or use the Copy operation when possible. For an odd N, we can handle the extra character using a Delete operation. The DP stores the minimum cost required to generate exactly N characters.
