Q1. 
Path Queries Problem Statement
Consider a weighted, undirected graph with 'V' vertices numbered from 1 to 'V' and 'E' bidirectional edges. You are tasked with handling 'Q' queries. For each query, you are...read more
Ans. 
Implement a function to find the shortest distance between two vertices in a weighted, undirected graph.
• Use Dijkstra's algorithm to find the shortest path between the given vertices.

• Create a graph data structure to represent the weighted, undirected graph.

• Handle cases where no path exists between the given vertices by returning -1.

• Optimize the algorithm to handle multiple queries efficiently.

• Consider edge cases such as...read more

Q2. 
Merge Sort Algorithm Problem Statement
Your task is to sort a sequence of numbers stored in the array ‘ARR’ in non-descending order using the Merge Sort algorithm.
Explanation:
Merge Sort is a divide-an...read more
Ans. 
Implement Merge Sort algorithm to sort a sequence of numbers in non-descending order.
• Divide the input array into two halves recursively

• Sort the two halves separately

• Merge the sorted halves to produce a fully sorted array

• Time complexity of Merge Sort is O(n log n)

• Example: Input - [5, 2, 9, 1, 5], Output - [1, 2, 5, 5, 9]

Q3. 
Rat in a Maze: All Paths Problem
You are provided with an N * N maze where a rat is positioned at starting cell MAZE[0][0]. The goal is to determine and print all possible paths that the rat can take to r...read more
Ans. 
Given an N * N maze with binary values, find and print all possible paths for a rat to reach the destination cell.
• Use backtracking to explore all possible paths from the starting cell to the destination cell.

• At each cell, check if it is a valid move (within bounds and not blocked), then recursively explore all four directions.

• Keep track of the path taken so far and mark the cells accordingly.

• Once the destination cell i...read more

Q1. 
The Skyline Problem
Compute the skyline of given rectangular buildings in a 2D city, eliminating hidden lines and forming the outer contour of the silhouette when viewed from a distance. Each building is ...read more
Ans. 
Compute the skyline of given rectangular buildings in a 2D city, eliminating hidden lines and forming the outer contour of the silhouette.
• Iterate through the buildings and create a list of critical points (x, y) where the height changes.

• Sort the critical points based on x-coordinate and process them to form the skyline.

• Merge consecutive horizontal segments of equal height into one to ensure no duplicates.

• Return the fin...read more

Q2. 
Rat in a Maze Problem Statement
You need to determine all possible paths for a rat starting at position (0, 0) in a square maze to reach its destination at (N-1, N-1). The maze is represented as an N*N ma...read more
Ans. 
Find all possible paths for a rat in a maze from source to destination.
• Use backtracking to explore all possible paths in the maze.

• Keep track of visited cells to avoid revisiting them.

• Recursively try moving in all directions (up, down, left, right) until reaching the destination.

• Return a list of strings representing valid paths sorted in alphabetical order.
