Q: What is the time complexity of merging two binary trees?
Solution: Merging two binary trees involves visiting each node, resulting in a time complexity of O(n), where n is the total number of nodes in both trees.
Steps: 5
Step 1: Understand that merging two binary trees means combining them into one tree.
Step 2: Realize that to merge the trees, you need to visit each node in both trees.
Step 3: Count the total number of nodes in both trees. Let's call this number 'n'.
Step 4: Since you visit each node once to merge them, the time taken is proportional to the number of nodes.
Step 5: Therefore, the time complexity for merging the two trees is O(n).
