• You have some water and some buckets to fill.

• Write a program called water_011.py that reads two lines of text from stdin.

• Line 1 contains a single integer, N, the number of litres of water available. N is in the range 0-1000.

• Line 2 lists the capacity in litres of one or more buckets. The capacity of each bucket is specified by a positive integer.

• Buckets must be filled in the order specified on line 2.

• Your program should output the number of buckets that can be completely filled before you run out of water.

• In this example we have 10 litres of water. We fill the first bucket (taking 6 litres), we fill the second bucket (taking another 2 litres) but we run out of water before we have completely filled the third bucket (it requires 5 litres). We output 2 (the number of buckets completely filled):
