( 21220 ) A Alternating Sum of Numbers PROGRAMMING implementation math 800

You are given a sequence of integers. Output the alternating sum of this sequence. In other words, output (a_1 - a_2 + a_3 - a_4 + a_5 - \dots). That is, the signs of plus and minus alternate, starting with a plus. The first line of the test contains one integer (t) ((1 \le t \le 1000)) — the number of test cases. Then follow (t) test cases. The first line of each test case contains one integer (n) ((1 \le n \le 50)) — the length of the sequence. The second line of the test case contains (n) integers (a_1, a_2, \dots, a_n) ((1 \le a_i \le 100)). Output (t) lines. For each test case, output the required alternating sum of the numbers.
