Sum Kind Of ProblemFor this problem, you will compute various running sums of values for positive integers. Input SpecificationThe first line of the input contains a single integer P (1 ≤ P ≤ 10 000), which is the number of data sets that follow. Each data set should be processed identically and independently. Each data set consists of a single line of input. It contains the data set number K, followed by an integer N (1 ≤ N ≤ 10 000). Output SpecificationFor each data set, there is one line of output. The single output line consists of the data set number K, followed by a single space, followed by three space-separated integers S1, S2, and S3, such that: S1 = The sum of the first N positive integers. S2 = The sum of the first N odd integers. S3 = The sum of the first N even integers. Sample Input
