Count number of occurrences in a sorted array using binary searchWe can also use a binary search. Using binary search we need o find two things, one is the first occurrence of the element and another is the last occurrence of the element....
Given a binary tree and an integer k, count the total number of paths in the tree whose sum of all nodes is equal to k. The path can be any path that is on the root-to-leaf path in the binary tree, or it can be a direct path from the root to a leaf.
