Can we use greedy approach in knapsack problem

#1

Why can’t we use greedy approach in this problem ?
We can sort the items as per their price and then try to pick up those taking care of the weight of the bag.

Is there some issue in this approach ?

try ur approach for this case->
weight -> 5 1 2 3 4
price -> 5 4 3 2 1

capacity-> 5.
