What is the output of the following code?
#include <iostream>
void printSubsetSum(int arr[], int size, int index, int sum, string subset) {
    if (index == size) {
        if (sum == 0) {
            cout << subset << " ";
        }
        return;
    }
    
    printSubsetSum(arr, size, index + 1, sum - arr[index], subset + to_string(arr[index]) + " ");
    printSubsetSum(arr, size, index + 1, sum, subset);
}
int arr[] = {1, 2, 3};
printSubsetSum(arr, 3, 0, 3, "");
  • a)
    1 2
  • b)
    1 2 3
  • c)
    1 2 3 1 2
  • d)
    1 2 3 1 2 3
Correct answer is option 'B'. Can you explain this answer?

What is the output of the following code?#include <iostream>void...
The printSubsetSum function prints all subsets of an array that sum up to a given target sum. It uses recursion to generate subsets by either including or excluding the current element at each step. The base case is when index is equal to size and sum is 0, in which case the current subset is printed. The function makes two recursive calls: one including the current element and subtracting its value from the sum, and another excluding the current element. Therefore, the output of printSubsetSum(arr, 3, 3, "") would be "1 2 3".
