We are given an n x m grid representing a parking lot. Each cell contains either a car or an empty space. Car are represented by a direction they are facing: 'N' (North), 'E' (East), 'S' (South), or 'W' (West). Empty spaces are denoted by '.'. A car can be moved if and only if the path direct in front of it is clear, meaning there are no other ...

The sample cases cover all possible scenarios for this problem. int main() { int x, y; cin >> x >> y; int result = 0; if(x > y) swap(x, y); if(x == y) result = 1; else if((y - x) % 2) result = 2; else result = 3; cout << result << endl; return 0; } </details>### Problem B - Piano Keys Track positions for le ...

Given an undirceted tree consisting of n nodes numbered from 0 to n - 1, each node has an associated value. The task is to compute for each node the nearest ancestor whose value is coprime with the current node's value. Two numbers are coprime if their greatest common divisor (GCD) is 1. The solution uses depth-first search (DFS) traversal stat ...

Problem A Given three integers A, B, and C, determine whether C falls within the range [A, B], i.e., check if A ≤ C ≤ B. Solution #include <bits/stdc++.h> using namespace std; int main() { int first, last, target; cin >> first >> last >> target; if (first <= target && target <= last) ...

Analyzing Graph Connectiivty Through Node Removal When removing a node from a graph, we need to calculate the impact on connectivity. Each removal can create multiple connected components, requiring careful tracking of these new components. Key Concepts Articulation Points: Nodes whose removal increases the number of connected components Compo ...

Nonlinear Data Structures Tree Structures Trees represent hierarchical data relationships. Binary trees contain nodes with up to two children, while multi-way trees can have more. The topmost node is called the root. A binary tree node typically contains: struct BinaryNode { int data; BinaryNode* leftChild; BinaryNode* rightChild; ...

Graph Connectivity Concepts A connected component in an undirected graph is a maximal subgraph where every pair of vertices is connected via a path. For directed graphs, a strongly connected component (SCC) is a maximal subgraph where every pair of vertices is mutually reachable via directed paths. SCCs are unique to directed graphs. In DFS tre ...

Maximum Island Area Problem Given a matrix of 1's (land) and 0's (water), calculate the maximum island area. Islands consist of adjacent land cells connected horizontally or vertically. Input: 4 5 1 1 0 0 0 1 1 0 0 0 0 0 1 0 0 0 0 0 1 1 Output: 4 The solution uses DFS or BFS to traverse each island component and count its area. Python Impleme ...

A - Swapping Two Integers Read two integers, swap their values, and output them on separate lines. B - Time Conversion Given N seconds where 0 ≤ N < 86400, convert it to 24-hour time format hh:mm:ss. The conversion formula using modular arithmetic: [N \equiv a_0 \times 3600 + a_1 \times 60 + a_2 \times 1 \pmod{86400}] Calculate hours, minute ...
