I have the following problem : I am given a tree with N apples, for each apple I am given it's weight and height,I can pick apples up to a given height H,each time I pick an apple the height of every apple is increased with U(also given).I have to find out the maximum weight of apples I can pick.

e.g:
N=4 H=100 U=10
(height-eight)
apple1: 91 10
apple2: 82 30
apple3: 93 5
apple4: 94 15

The answer is 45 : I first pick the apple with the weight of 15 then the one with the weight of 30.

I would like to know if someone here could help me with giving me an hint on how I should approach this problem.

Thank you.
