Solve among these: Fibonacci modified, maximum subarray, red john is back, longest increasing subsequence and longest common subsequence. These are easy.

For those who want to get an idea of dp and some problems where it is used,

The ranking system in Short and LunchTime contests is just plain wrong. The time should be measured from when the person has entered the contest and not from when the contest has started. e.g. if person A solves problem in 1hr and person B solves it in 5min but entered contest late, person A is given higher rank than person B which from my perspective is wrong and partial. Most of other websites e.g Hackerrank and Hackerearth use it like thi. Please look in this matter. Sorry for commenting here but I am not allowed to ask a question due to lower karma points.
