```java
class Demo {

public static void main(String[] args) {
new Demo().func();
}

public void func() {
List<List<Integer>> res = new ArrayList<>();
List<List<Integer>> sourceList = new ArrayList<>();
sourceList.add(Arrays.asList(0, 1, 2));
sourceList.add(Arrays.asList(0, 1));
sourceList.add(Arrays.asList(0, 1, 2, 3, 4));
dfs(sourceList, res, new ArrayList<>(), 0);
System.out.println(res);
}

public void dfs(List<List<Integer>> sourceList, List<List<Integer>> res, List<Integer> curList, int index) {
if (index == sourceList.size()) {
res.add(new ArrayList<>(curList));
} else {
List<Integer> source = sourceList.get(index);
for (Integer i : source) {
curList.add(i);
dfs(sourceList, res, curList, index + 1);
curList.remove(curList.size() - 1);
}

}
}

}

public static List<List<Integer>> cal(int[] arr, int target) {
List<List<Integer>> results = new ArrayList<>();
func(results, new ArrayList<>(), arr, target, 0);
return results;
}

public static void func(List<List<Integer>> results, List<Integer> curList, int[] arr, int target, int start) {
int num = curList.stream().mapToInt(value -> value).sum();
if (num > target) {
return;
}

if (num == target) {
results.add(new ArrayList<>(curList));
} else {
for (int i = start; i < arr.length; i++) {
curList.add(arr[i]);
func(results, curList, arr, target, i);
curList.remove(curList.size() - 1);
}
}
}
