( 46928 ) A Sublime Sequence PROGRAMMING brute force math

Farmer John has an integer (x). He creates a sequence of length (n) by alternating integers (x) and (-x), starting with (x). For example, if (n = 5), the sequence looks like: (x, -x, x, -x, x). He asks you to find the sum of all integers in the sequence. The first line contains an integer (t) ((1 \leq t \leq 100)) — the number of test cases. The only line of input for each test case is two integers (x) and (n) ((1 \leq x, n \leq 10)). For each test case, output the sum of all integers in the sequence.
