i think this prob cannot be solved by DP then... Because anytime a new value coming into the non decreasing sub-array obtained by the DP equation can be disrupted(like in the above example). I think a backtracking approach cud prove useful. (Recursion) anytime we get a new element we can do two things : Either delete it or decrement the previous values equal to it. We do both by calling the same function twice for each element. Plz comment on this...
