Depth of node
Easy Accuracy: 50.1% Submissions: 2044 Points: 2

Given a binary tree, find the depth of the deepest odd level leaf node in a binary tree. If there is no leaf at odd level then return 0.
Consider that level starts with 1. Depth of a leaf node is number of nodes on the path from root to leaf (including both leaf and root).

Input Format:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case contains an integer n denoting the number of edges. The next line contains the edges of the binary tree.

Output Format:
Print the depth of the deepest odd level leaf node in the binary tree.

You don't need to read input/output. Complete the function depthOfOddLeafUtil

Constraints:
1<=T<=1000
1<=n<=1000
1<=data of node<=1000
