Chef visited a grocery store for fresh supplies. There are N items in the store where the i^{th} item has a freshness value A_{i} and cost B_{i}.

Chef has decided to purchase all the items having a freshness value greater than equal to X. Find the total cost of the groceries Chef buys.

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

- The first line of input will contain a single integer T, denoting the number of test cases.
- Each test case consists of multiple lines of input.
- The first line of each test case contains two space-separated integers N and X — the number of items and the minimum freshness value an item should have.
- The second line contains N space-separated integers, the array A, denoting the freshness value of each item.
- The third line contains N space-separated integers, the array B, denoting the cost of each item.

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

For each test case, output on a new line, the total cost of the groceries Chef buys.

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

$1 ≤ T ≤ 100$
$1 ≤ N, X ≤ 100$
$1 ≤ A_{i}, B_{i} ≤ 100$

----- explanation 1 ------ 
Test case $1$: Item $2$ has freshness value greater than equal to $X = 20$. Thus, Chef buys item $2$. The total cost is $90$.

Test case $2$: Items $1, 2,$ and $3$ have freshness value greater than equal to $X = 1$. Thus, Chef buys all $3$ items. The total cost is $1+2+3 = 6$.

Test case $3$: No item has freshness value greater than equal to $X = 100$. Thus, Chef buys no items.

Test case $4$: Items $2$ and $3$ have freshness value greater than equal to $X = 50$. Thus, Chef buys items $2$ and $3$. The total cost is $30+20 = 50$.
