Create a method that performs various operations on two sets of integers and returns the results in a map. The operations to implement are:
- Union - all elements that are in either set
- Intersection - only elements that are in both sets
- Difference - elements that are in the first set but not in the second
- Symmetric Difference - elements that are in either set but not in both
Examples:
Input: set1 = {1, 2, 3}, set2 = {3, 4, 5}
Output: {
'union' => {1, 2, 3, 4, 5},
'intersection' => {3},
'difference' => {1, 2},
'symmetricDifference' => {1, 2, 4, 5}
}
Input: set1 = {10, 20, 30}, set2 = {40, 50, 60}
Output: {
'union' => {10, 20, 30, 40, 50, 60},
'intersection' => {},
'difference' => {10, 20, 30},
'symmetricDifference' => {10, 20, 30, 40, 50, 60}
}
