Given a tree, and the weights of all the nodes and an integer x, the task is to find a node i such that |weight[i] – x| is minimum.
x = 15
Node 1: |5 – 15| = 10
Node 2: |10 – 15| = 5
Node 3: |11 -15| = 4
Node 4: |8 – 15| = 7
Node 5: |6 -15| = 9
Approach: Perform dfs on the tree and keep track of the node whose weighted absolute difference with x gives the minimum value.
Below is the implementation of the above approach:
- Find the node whose absolute difference with X gives maximum value
- Find the minimum absolute difference in two different BST's
- Pair with minimum absolute difference | BST
- Minimum absolute difference between N and a power of 2
- Pair with minimum absolute difference after solving each query
- Find the node whose xor with x gives minimum value
- Minimum cost path from source node to destination node via an intermediate node
- Find the node whose sum with X has minimum set bits
- Find the node with minimum value in a Binary Search Tree
- Find the node with minimum value in a Binary Search Tree using recursion
- Minimum edges to be added in a directed graph so that any node can be reachable from a given node
- Check whether the sum of absolute difference of adjacent digits is Prime or not
- Count maximum elements of an array whose absolute difference does not exceed K
- Arrange first N natural numbers such that absolute difference between all adjacent elements > 1
- Replace elements with absolute difference of smallest element on left and largest element on right
