Description
You are given three positive integers n, m, and k, which represent the exact number of characters 0, 1, and 2 available, respectively. You want to construct the longest possible palindrome string S using at most n zeros, m ones, and k twos. Compute and print the maximum possible length of such a palindrome. A palindromic string reads the same forward and backward. Few examples of such palindromes - 0, 1, 2, 11, 00, 101, 121 etc.
Input
- The first line contains a single integer
T(1 ≤ T ≤ \(10^5\)), the number of test cases. - Each of the next
Tlines contains three space-separated integersn,m,k.(1 ≤ n, m, k ≤ \(10^9\))
Output
- For each test: Print the length of longest palindrome string
Syou have made.

First test case :
String S="2120212", is a palindromic string. Where at most n=1 zero, m=2 ones and k=4 twos.
The length of the string S is 7 which is maximum.
