## A Subtask Problem solution codechef

Chef recently solved his first problem on CodeChef. The problem he solved has N test cases. He gets a score for his submission according to the following rules:

1) If Chef’s code passes all the N test cases, he gets 100 points.

2) If Chef’s code does not pass all the test cases, but passes all the first M(M<N) test cases, he gets K(K<100) points.

3) If the conditions 1 and 2 are not satisfied, Chef does not get any points (i.e his score remains at 0 points).

You are given a binary array A1,A2,,AN of length N, where Ai=1 denotes Chef’s code passed the ith test case, Ai=0 denotes otherwise. You are also given the two integers M,K. Can you find how many points does Chef get?

### A Subtask Problem solution codechef Explanation

Test case 1: Chef’s code neither passes all 4 test cases nor passes the first 2test cases. Hence he does not get any points.

Test case 2: Chef’s code does not pass all 3 test cases, but passes the first 2test cases. Hence he gets 50 points.

Test case 3: Chef’s code passes all the 4 test cases. Hence he gets 100 points.
