WebAll the nodes with are at distance 1, meaning the adjacent nodes are [1, 4, 5]. Explanation 2: The given tree is same, and [3] is the only node with distance 2. Note: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. WebJun 14, 2024 · The third is "kFrom[A][k] = set of nodes k distance from A", since k is valid from 0 to the max distance, an hashmap/dictionary to an array/list could be used here rather than a nested hashmap/dictionary. This allows for space and time efficient*** creating the set of nodes with distance <= k from A.
