Sam has recently started his own company known as Codage etoile. He cares a lot about his employees. Due to high work load, he buys some special types of energy boosters for his employees. There are N different types of energy boosters. Each energy booster provides the capacity Ci where Ci is the capacity of the ith booster. There are fi bottles of ith booster.
A person gets the cumulative capacity of all the boosters consumed. That is, if a person drinks 2 bottles, one of an energy booster with capacity 2 units and another of an energy booster with capacity 3 units, it will give him/her a cumulative capacity of 5 units. Sam wants to find the count of distinct capacities, between 1 to K (inclusive), which can be achieved on drinking these boosters. For sake of convenience, count of distinct capacities is labelled as 'CDC'.
$$$1 <= N <= 100$$$
$$$1 <= K <= 15*1e5$$$
$$$1 <= fi <= 1000,$$$ $$$where$$$ $$$1 <= i <= N$$$
$$$1 <= Ci <= 1e5,$$$ $$$where$$$ $$$1 <= i <= N$$$
Sample Input 1:
3 1 2 3 3 1 2 1 6
Sample Output 1: 6
I am not able to solve this problem, can someone please help.
