Asteroid Collision LeetCode Solution – We are given an array asteroidsof integers representing asteroids in a row. For each asteroid, the absolute value represents its size, and the sign represents its direction (positive meaning right, negative meaning left). Each asteroid moves at the same speed. Find out the state of the asteroids after all coll...
Intuition According to the question, positive values are moving to the right and negative values are moving to the left. We can apply the concept of relative velocity and make positive values as fixed and negative values now moving with double velocity in the negative direction. But, the magnitude of velocity does not matter only the direction matt...
Time Complexity:O(n). Gone n. Then traversed back n, and popped all stack. Space Complexity: O(n). Stack size. All asteroids are on the stack.
class Solution { public: vector<int> asteroidCollision(vector<int>& asteroids) { vector<int> stack; for (const int a : asteroids) if (a > 0) { stack.push_back(a); } else { // a < 0 // Destroy the previous positive one(s). while (!stack.empty() && stack.back() > 0 && stack.back() < -a) stack.pop_back(); if (stack.empty() || stack.back() < 0) stac...
