A factory has N Product Quality Analysts (PQA) working in a single line. The first PQA is standing at the start of the product line and the N° PQA is standing at the end of the product line. The first PQA starts the checking of a product and takes t, minutes and then hands it over to the 2PQA More formally, the IPQA takes t, minutes time to check a product and then hand it over to the (i+1) PQA When, the N" PQA completes his inspection for a product, we call the product a "Verified Product". In this problem, you have to calculate how much time it requires to verify the first K products. For example, Let there be 4 PQAS working in the factory and they take 2, 3, 1, and 4 minutes time respectively to check a product Product checking timeline these PQA is as follows: Product 1 Product 2 Product Start of checking End of checking Start of checking End of checking By PQA, By PQA, By PQA, By PQA, 1 3 6 7 2 5 6 10 6 11 14 3 8 9 So, the first product will be verified at the end of 10 minutes, and the second product will be verified at the end of 14 minutes. Input Input starts with an integer T(15 T 51001) denoting the number of test cases. Each of the test cases starts with two integers N (1 S N s 20) and K (1 5 Ks 10%). The next line of the test case will contain N space-separated integers t, ...L (1 51510). Output The output should be in the format "Case X: Y' where X is the case number and Y is the time when the K product will be verified. Please see the output in the sample case for more clarity.

Transcribed Image Text:J
A factory has N Product Quality Analysts (PQA) working in a single line. The first PQA is standing at the
start of the product line and the N PQA is standing at the end of the product line. The first PQA starts the
checking of a product and takes t, minutes and then hands it over to the 2nd PQA.
More formally, the IPQA takes t, minutes time to check a product and then hand it over to the (i+1) PQA.
When, the N™ PQA completes his inspection for a product, we call the product a "Verified Product".
In this problem, you have to calculate how much time it requires to verify the first K products.
For example, Let there be 4 PQAS working in the factory and they take 2, 3, 1, and 4 minutes time
respectively to check a product. Product checking timeline these PQA is as follows:
Product
1st Product
Problem J

So, the first product will be verified at the end of 10 minutes, and the second product will be verified at the
end of 14 minutes.
Output for Sample Input
Case 1: 14
Case 2: 23
Input
Input starts with an integer T(1≤ T ≤1001) denoting the number of test cases. Each of the test cases starts
with two integers N (1 ≤ Ns 20) and K (1 ≤ K≤ 10¹9). The next line of the test case will contain
space-separated integers t₁, ... (1410)
Output
The output should be in the format "Case X: Y' where X is the case number and Y is the time when the
K™ product will be verified. Please see the output in the sample case for more clarity.
