Write a Java program to list all the k-element subsets of the set {1,2,..,n}, where k<=n. Inputs to your program will be the positive integers n and k and the output will be a list of subsets of size k for the set {1,2,.,n}. Please test the program before posting it and provide a screenshot of the output if possible so I can understand it better. The program needs to ask for input of N and K.
