Solution: Reaching Points
Understand how to solve the reaching points problem by working backwards from the target using a modulo-based approach derived from modified binary search. Learn to efficiently check transformations and optimize steps to meet coding interview expectations.

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:
