Write a program to receive a set (in format of a sequence of numbers) and print all subsets of that set The program must handle repetitive numbers. For example, if there are 5 "one"s in the input, it should merge them to a single "one". . If there is anything other than numbers in the input, it should print " not a valid input". Assume all numbers in the input are integers (and less than memory of int) In output, print each subset in a separate line The program should print0in the first line, and then should print subsets of size 1, then subsets of size 2, and so on. Example Input: 1,2,3,1,6,3,6,2 output: * f1) * 12) 13) 16) Write a program to receive a set (in format of a sequence of numbers) and print all subsets of that set The program must handle repetitive numbers.
