There exists an infinitely large grid. You are currently at point (1, 1), and you need to reach the point (targetX, targetY) using a finite number of steps.
In one step, you can move from point (x, y) to any one of the following points:
(x, y - x)(x - y, y)(2 * x, y)(x, 2 * y)Given two integers targetX and targetY representing the X-coordinate and Y-coordinate of your final position, return true if you can reach the point from (1, 1) using some number of steps, and false otherwise.
Example 1:
Input: targetX = 6, targetY = 9 Output: false Explanation: It is impossible to reach (6,9) from (1,1) using any sequence of moves, so false is returned.
Example 2:
Input: targetX = 4, targetY = 7 Output: true Explanation: You can follow the path (1,1) -> (1,2) -> (1,4) -> (1,8) -> (1,7) -> (2,7) -> (4,7).
Constraints:
1 <= targetX, targetY <= 109
