Implement a graph data structure in Java and write a method to perform a depth-first search (DFS) starting from a given vertex.
Algorithms & Data Structures TASK Given an array of integers, find all possible subsets of the array. For example, if the input array is [1, 2, 3], the output should be [], [1], [2], [3], [1,2], [1,3], [2,3], [1,2,3].
