## Dynamic Programming (DP) [Problemset]

Prerequisits:

- Arrays and loops

This Tutorial Includes:

- An introduction dynamic programming
- The solution to 698A
- A simple, commented code with the same variable names as the explanation in the video

Prerequisits:

- Arrays and loops

This Tutorial Includes:

- An introduction dynamic programming
- The solution to 8555B
- A simple code with the same variable names as the explanation in the video

Problem 3: Codeforces 961B (Prefix sums)

Problem 5: Codeforces 939C (Prefix sums)

Problem 7: Codeforces 22B (This problem can be solved in O ( (NM)^{3}) with brute force but there is a dp O ( (NM)^{2}) solution.)

Problem 10: Codeforces 245H **(The solution without hashing.)**

Prerequisits:

- Understand the (very basic) idea behind dp

This Tutorial Includes:

- Finding all the palindromes in a string
- 2D Prefix sums
- Simple code (no defines, etc) that matches the tutorial and an explination of every line
**(helps with the implementation)**

Prerequisits:

- for each loops
- arrays and vectors

This Tutorial Includes:

- An introduction trees
- The solution to 839C
- Simple code (no defines, etc) that matches the tutorial and a line-by-line explanation of the code while I write it (helpful for those stuck on the implementation of DFS)
