( 42645 ) A Cards for Friends PROGRAMMING greedy math

B'For the New Year, Polycarp decided to send postcards to all his n friends. He wants to make postcards with his own hands. For this purpose, he has a sheet of paper of size w x h , which can be cut into pieces. Polycarp can cut any sheet of paper w x h that he has in only two cases: If w and h are even at the same time, then Polycarp can cut the sheet according to any of the rules above. After cutting a sheet of paper, the total number of sheets of paper is increased by 1 . Help Polycarp to find out if he can cut his sheet of size w x h at into n or more pieces, using only the rules described above. The first line contains one integer t ( 1 <= t <= 10^4 ) -- the number of test cases. Then t test cases follow. Each test case consists of one line containing three integers w , h , n ( 1 <= w, h <= 10^4, 1 <= n <= 10^9 ) -- the width and height of the sheet Polycarp has and the number of friends he needs to send a postcard to. For each test case, output on a separate line: You can output "YES" and "NO" in any case (for example, the strings yEs, yes, Yes and YES will be recognized as positive). In the first test case, you can first cut the 2 x 2 sheet into two 2 x 1 sheets, and then cut each of them into two more sheets. As a result, we get four sheets 1 x 1 . We can choose any three of them and send them to our friends. In the second test case, a 3 x 3 sheet cannot be cut, so it is impossible to get two sheets. In the third test case, you can cut a 5 x 10 sheet into two 5 x 5 sheets. In the fourth test case, there is no need to cut the sheet, since we only need one sheet. In the fifth test case, you can first cut the 1 x 4 sheet into two 1 x 2 sheets, and then cut each of them into two more sheets. As a result, we get four sheets 1 x 1 . '...
