yes ..19 is the correct answer.

p(f1)
   /  \
 p1   p
 (f2)  (f2)
/ \   /
\
   /   \ /
\
 p2  p1  p11
p(f3)
 (f4)  (f3)
(f4)/\
/  \ /\
/\   /  \
   /\   /  \
/  \  /   \
p3   p2 p6 p1
f5f5   f4  f5
 and so on
if fork2 returns zero then fork3 is not executed.

Re: [algogeeks] Re: Amazon interview Question (Array yet again!)

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...
