We are given
struct NodeProp {
int id;
int parent_id;
int weight;
};
Example:
100 {parent_id: -1, weight: 5}
|
10 {parent_id: 100, weight: 3}
|
5 {parent_id: 10, weight: 2}
We have to print the sum of weights for each id
For example if the id=5 parent_id- 10 and weight = 4 then id = 10 weight
should be 7
and 100 should be 12
What is the best data structure to use for the above and how do we proceed
for the solution?
