Cameras In Binary Tree
1. You are given a partially written function to solve. 2. You are required to complete the body of MinCamerasInBT_ function. The function is expected to return integer value representing minimum number of camera(s) required for the coverage of complete tree. 3.A camera is placed on any node will ensure coverage of parent-node as well as it's child-node(s), if any. 4. Input and Output is managed for you.
0 <= Number of Nodes <= 10^9 -10^9 <= value of Node data <= 10^9
Input is managed for you.
