Python: Get all possible unique subsets from a set of distinct integers

Python Class: Exercise-4 with Solution

Write a Python program to get all possible unique subsets from a set of distinct integers.

Sample Solution:

Python Code:

class py_solution:
    def sub_sets(self, sset):
        return self.subsetsRecur([], sorted(sset))
    
    def subsetsRecur(self, current, sset):
        if sset:
            return self.subsetsRecur(current, sset[1:]) + self.subsetsRecur(current + [sset[0]], sset[1:])
        return [current]

print(py_solution().sub_sets([4,5,6]))

Sample Output:

[[], [6], [5], [5, 6], [4], [4, 6], [4, 5], [4, 5, 6]]

Previous: Write a Python program to find validity of a string of parentheses, '(', ')', '{', '}', '[' and ']. These brackets must be close in the correct order,
for example "()" and "()[]{}" are valid but "[)", "({[)]" and "{{{" are invalid.

Next: Write a Python program to find a pair of elements (indices of the two numbers) from a given array whose sum equals a specific target number.
