WebJan 5, 2024 · Given a binary tree, write a program to count the number of Single Valued Subtrees. A Single Valued Subtree is one in which all the nodes have same value. Expected time complexity is O (n). Example: Input: root of below tree 5 / \ 1 5 / \ \ 5 5 5 Output: 4 There are 4 subtrees with single values.
