Solution: Reaching Points
Understand how to solve the points transformation problem by applying a modified binary search technique working backwards from the target to the source. Learn to use modulo operations to optimize the algorithm and reduce time complexity to logarithmic scale while maintaining constant space usage.

Statement
Given four integers sx, sy, tx, and ty, determine whether it is possible to transform the point (sx, sy) into the point (tx, ty) through any number of operations. Return true if such a transformation is possible, or false otherwise.
At each step, a point (x, y) can be transformed into either (x, x + y) or (x + y, y).
Constraints:
