Answer #1
Weight 3 2 1 4
Profit 40 6 20 12
item no 1 2 3 4
DP solu. 1 0 1 0

Note1: Comparing all leaf nodes possibility ,solution according to dynamic programming is (1,0,1,0)

(0,0) (12,4) (20,1) (32,5) (6,2) (18,6) (26,3) (38,7) (40,3) (52,7) (60,4) (72,8) (46,5) (58,9) (66,6) (78,10)

// Red mark are invalid bez w=5

(0,0) (12,4) (20,1) (32,5) (6,2) (26,3) (40,3) (60,4) (46,5)

// among this  (60,4) is giving solution according to dynamic programming.

Note2: we can solve this by table method also but in this way(tree) we can explore dynamic programming more efficiently.
