## Problem Statement

#### There are ‘N’ games. You are given two arrays, ‘A’ and ‘B’ of length ‘N’ such that ‘A[ i ]’ represents the score you get for purchasing the ‘i-th’ game, and ‘B[ i ]’ represents the cost of the ‘i-th’ game.

#### Define ‘M’ to be the highest cost paid among all games you bought.

#### Return the minimum ‘M’ such that you can get a total score of at least ‘X’ if you can purchase exactly one game for free. Return ‘-1’ if it is impossible.

##### For Example :

```
Let 'N' = 3, 'A' = [ 3, 7, 1 ], 'B' = [ 2, 4, 4 ], 'X' = 9.
We buy the second game for free and the first for a cost of '2'.
The total score is '3 + 7 = 10', and the value of 'M' is 2.
It can be shown that this is the minimum 'M' possible.
Thus, the answer is '2'.
```

##### Constraints :

```
1 <= 'T' <= 10
1 <= 'N' <= 10^5
1 <= 'X, A[i], B[i]' <= 10^9
Time Limit: 1 sec
```

##### Sample Input 1 :

```
2
3 11
4 2 6
14 7 7
3 100
11 3 5

##### Sample Output 1 :

```
7
-1
```

##### Explanation Of Sample Input 1 :

```
First test case:-
We buy the first game for free and the other two games for a cost of '7' each.
The total score is '4 + 2 + 6 = 12', and the value of 'M' is 7.
It can be shown that this is the minimum 'M' possible.
Thus, the answer is '7'.
Second test case:-
It can be shown that it is impossible to get a total score of at least 'X'.
Thus, the answer is '-1'.
```

##### Sample Input 2 :

```
2
5 17
5 4 3 1 6
10 11 12 13 14
4 30
