CF2134A.Painting With Two Colors
Painting With Two Colors
You are given three positive integers , , and ().
Consider a row of cells, initially all white and indexed from to . You will perform the following two steps in order:
- Choose an integer such that , and paint the consecutive cells red.
- Choose an integer such that , and paint the consecutive cells blue.
If a cell is painted both red and blue, its final color is blue.
A coloring of the grid is considered symmetric if, for every integer from to (inclusive), the color of cell is the same as the color of cell . Your task is to determine whether there exist integers and such that the final coloring of the grid is symmetric.
Input
Each test contains multiple test cases. The first line contains the number of test cases (). The description of the test cases follows.
The first and the only line of each test case contains three integers , , and (, ) — the number of cells of the grid and the number of cells to be painted in each step.
Output
For each testcase, output "YES" if it is possible that the final coloring of the grid is symmetric; otherwise, output "NO".
You can output the answer in any case (upper or lower). For example, the strings "yEs", "yes", "Yes", and "YES" will be recognized as positive responses.
Note
In the first test case, the grid becomes symmetric when choosing and , so the answer is "YES". The following figure illustrates each step of the coloring process:

In the second test case, the grid becomes symmetric when choosing and , so the answer is "YES". The following figure illustrates each step of the coloring process:

In the third and fourth test cases, it can be proved that no choice of and results in a symmetric grid, so the answer is "NO".
