Dijkstra's Shortest Path Problem
Given an undirected graph with ‘V’ vertices (labeled 0, 1, ... , V-1) and ‘E’ edges, where each edge has a weight representing the distance between two connected nodes (X,...
- Ans. Using Adjacency Matrix
The idea is to maintain two arrays, one stores the visited nodes, and the other array stores the distance (element at index ‘i’ denotes the distance from node 0 to node ‘i’). We pick an unvisited minimum distance vertex, then update the distance of all its adjacent vertices considering the path from source to an adjacent vertex to pass through the picked minimum distance vertex. Repeat the process...

Input:
The input starts with an integer 'T' representing the number of test cases. Each test ...
- Ans. Recursive
For each boundary, we will use the 4 loops. Now the problem is reduced to print the remaining submatrix which is handled with the help of recursion. Keep track of new dimensions(rows and columns) of the current submatrix which are passed with the help of parameters in each recursion call.
Algorithm:

0/1 Knapsack Problem Statement
A thief is planning to rob a store and can carry a maximum weight of 'W' in his knapsack. The store contains 'N' items where the ith item has a weight of 'wi' and a value of...
- Ans. Dynamic Programming
Approach: In the Dynamic programming we will work considering the same cases as mentioned in the recursive approach. In a DP[][] table let’s consider all the possible weights from ‘1’ to ‘W’ as the columns and weights that can be kept as the rows.
The state DP[i][j] will denote maximum value of ‘j-weight’ considering all values from ‘1 to ith’. So if we consider ‘wi’ (weight in ‘ith’ row) we can...
