Given n items of different weights and bins each of capacity c, assign each item to a bin such that number of total used bins is minimized. It may be assumed that all items have weights smaller than bin capacity.


Example:
Input: weight[] = {4, 8, 1, 4, 2, 1}
Bin Capacity c = 10
Output: 2
We need minimum 2 bins to accommodate all items
First bin contains {4, 4, 2} and second bin {8, 1, 1}

Input: weight[] = {9, 8, 2, 2, 5, 4}
Bin Capacity c = 10
Output: 4
We need minimum 4 bins to accommodate all items.

Input: weight[] = {2, 5, 4, 7, 1, 3, 8};
Bin Capacity c = 10
Output: 3

#WAP TO REVERSING A LIST IN PYTHON

#METHOD-01:

# Reversing a list using reversed()
def Reverse(lst):
return [ele for ele in reversed(lst)]

# Driver Code
lst = [10, 11, 12, 13, 14, 15]
print(Reverse(lst))


#METHOD-02:

# Reversing a list using reverse()
def Reverse(lst):
lst.reverse()
return lst

lst = [10, 11, 12, 13, 14, 15]
print(Reverse(lst))


METHOD-03:

# Reversing a list using slicing technique
def Reverse(lst):
new_lst = lst[::-1]
return new_lst

lst = [10, 11, 12, 13, 14, 15]
print(Reverse(lst))
