Problem Description

Your task is to calculate the sum of some integers.

Input

Input contains an integer N in the first line, and then N lines follow. Each line starts with a integer M, and then M integers follow in the same line. 

Output

For each group of input integers you should output their sum in one line, and you must note that there is a blank line between outputs.

Sample Input

34 1 2 3 45 1 2 3 4 53 1 2 3

Sample Output

10156
