Chef has a garden containing N cells. The i-th cell has R_{i} red flowers and B_{i} blue flowers. Chef can collect only one type of flowers (either red or blue) from each cell.

Let X denote the total number of red flowers Chef collects and Y denote the total number of blue flowers Chef collects. Chef wants to maximize the value of \mathrm{min}(X, Y). Can you help Chef?

------ Input Format ------ 

- The first line contains a single integer T — the number of test cases. Then the test cases follow.
- The first line of each test case contains an integer N — the number of cells in Chef's garden.
- The second line of each test case contains N space-separated integers R_{1}, R_{2}, \dots, R_{N} denoting the number of red flowers in each cell.
- The third line of each test case contains N space-separated integers B_{1}, B_{2}, \dots, B_{N} denoting the number of blue flowers in each cell.

------ Output Format ------ 

For each test case, output the maximum value of \mathrm{min}(X, Y).

------ Constraints ------ 

$1 ≤ T ≤ 100$
$1 ≤ N ≤ 100$
$1 ≤ R_{i}, B_{i} ≤ 200$
- The sum of $N$ over all test cases does not exceed $100$.

----- explanation 1 ------ 
Test case 1:
If Chef collects $101$ red flowers from the cell, Chef will have a total of $101$ red flowers $(X = 101)$ and $0$ blue flowers $(Y = 0)$. 
If Chef collects the $3$ blue flowers from the cell, Chef will have a total of $0$ red flowers $(X = 0)$ and $3$ blue flowers $(Y = 3)$. 
Either way, $\mathrm{min}(X, Y) = 0$, the answer is $0$.

Test case 2: Chef collects the $199$ blue flowers from the first cell and the $200$ red flowers from the second cell, so $\mathrm{min}(X, Y) = 199$, which is maximum.

Test case 3: Chef collects blue cells from the first three cells $(Y = 3 + 1 + 3)$ and red flowers from the fourth cell $(X = 10)$, so $\mathrm{min}(X, Y) = 7$, which is maximum.
