I just started with the dynamic programming and tried to solve codechef problems based on dp tag from highest no. of submissions but they are too hard. can anyone give me link to some good dp problems so that I can master dp. and how to approach dp problems??
First try some well known dp problems then move on to questions and try to convert/compare them into/with these problems.
- Some well known dp problems with tutorial- http://people.cs.clemson.edu/~bcdean/dp_practice/
- Look under dynamic programming- http://www.geeksforgeeks.org/top-algorithms-and-data-structures-for-competitive-programming/#algo2
- A video lecture I found interesting for starters- https://www.youtube.com/watch?v=sF7hzgUW5uY
- Top Coder tutorial blog- https://www.topcoder.com/community/data-science/data-science-tutorials/dynamic-programming-from-novice-to-advanced/
- questions:-
(i).https://www.hackerrank.com/domains/algorithms/dynamic-programming/difficulty/all/page/1
(ii).http://codeforces.com/problemset/tags/dp/page/1?order=BY_SOLVED_DESC#
(iii).Some dp problems I solved recently on cc and found easy for newbies:
https://www.codechef.com/problems/A1
https://www.codechef.com/problems/FROGV
https://www.codechef.com/problems/KSPHERES
Try HACKERRANK problems FIRST as they are based on well known dp problems.
Hope this helps.
Happy Coding
