In high school we learned about various series and how to compute a formula for a series. In this problem we will apply that knowledge and compute the sum of a series up to n^th term of that series. The series that we are going to consider is: 1³ + 2³ + 3³ + 4³ + 5³ + ... + n³ We have to find out the sum of this series up to n^th item where n will be given as input in the program. You can always be sure that the end result will fit in 32 bit signed integer. Input: ------ Input starts with an integer **T (1 <= T <= 200)**, denoting the number of test cases. Each case contains an integer **N (1 ≤ N ≤ 300)** denoting the n^th item up to which you have to calculate the sum. Output: ------- For each case of input, print the case number as "Case #:" and then print the sum of the n items of the series in a single line. *Please check sample input/output for better understanding of the format.* Sample Input ------------ 3 1 3 11 Sample Output ------------- Case 1: 1 Case 2: 36 Case 3: 4356
