Can you provide a code to bin Packing Problem ( Minimize number of used Bins ) and the other steps required given the following:
Bin Packing Problem ( Minimize number of used Bins ) | Returns number of bins required using first fit online algorithm.
Initialize result ( Count of bins ).
Create an array to store remaining space in bins there can be at most n bins.
Place items one by one.
Find the first bin that can accommodate weight [ i ].
Initialize minimum space left and index of best bin.
If no bin could accommodate weight [ i ] , create a new bin.
else : Assign the item to best bin.
Driver code"
How can the above be solved in Python?
