Why is this getting WA? (CHEFAPAR)

Here is my code: https://www.codechef.com/viewsolution/15902557
I can’t understand, where am I wrong in my approach?
Could someone please help me correct my code?

Thanks a lot!

Consider this case-

1 1 0

The answer is 1100, but your code will print 1300 if I am not wrong.

According to below test cases it should be fine.

@Test
public void testInitialCases() {
	assertEquals(0, CHEFAPAR.calculateDues("1 1"));
	assertEquals(2200, CHEFAPAR.calculateDues("0 0"));
	assertEquals(2300, CHEFAPAR.calculateDues("0 1 0"));
	assertEquals(1200, CHEFAPAR.calculateDues("0 1"));
	assertEquals(1100, CHEFAPAR.calculateDues("1 1 0"));
	assertEquals(2300, CHEFAPAR.calculateDues("1 0 0 1"));
}

Hey vijju my question is irrelevant to your answer but do you know about overloading operators?

A little bit. Drop me a mail where you need help, or refer here - http://www.geeksforgeeks.org/operator-overloading-c/

I sent you an email discussing about my problem please look at it thank you

https://www.codechef.com/viewsolution/16628058 Look at my approach if it helps!!

In this problem, you just need to find the first occurrence of ‘0’ because if you’re late for one month then there is no way you can pay the maintenance fees on time. so first just run a simple for loop to see where you didn’t pay the fees and keep adding the fees which is 1000. and then at the end add ((N-first occurrence of 0)*100) to your fees. Hope it helps!!

You are right, thanks for your answer. According to your advice i understand why my code is failed, i changed my code and answer is accepted.
