Obstacle Placement and Range Checking

On a number line, execute the following operations: [1, x]: Place an obstacle at position x [2, x, size]: Check if a structure of size centered at x can be built Output '1' if possible, '0' if not. Input: [ [1, 5], [2, 5, 3], [1, 7], [2, 5, 6] ] Output: [1, 0] Obstacles and number line positions do not exceed 10^9. Example Input [ [1, 5], [2, 5, 3], [1, 7], [2, 5, 6] ]
