Asteroid Collision LeetCode Solution - Given array of integers representing asteroids in a row. Find out state of asteroids after collisions.
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...
Asteroid Collision - We are given an array asteroids of 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.
