 # Find the closest pair from two sorted arrays

Given two sorted arrays of distinct integers, A and B, and an integer C,
find and return the pair whose sum is closest to C and the pair has one element from each array.

More formally, find A[i] and B[j] such that abs((A[i] + B[j]) - C) has minimum value.

If there are multiple solutions find the one with minimum i and even if there are multiple values of j
for the same i then return the one with minimum j.

Note: Return an array with two elements {A[i], B[j]}.

Input Format

``````The first argument given is the integer array A.
The second argument given is the integer array B.
The third argument given is integer C.
``````

Output Format

``````Return the pair which has sum closest to C.
``````

Constraints

``````1 <= length of both the arrays <= 100000
1 <= A[i], B[i] <= 10^9
1 <= C <= 10^9
``````

For Example

``````Input 1:
A = [1, 2, 3, 4, 5]
B = [2, 4, 6, 8]
C = 9
Output 1:
[1, 8]

Input 2:
A = [5, 10, 20]
B = [1, 2, 30]
C = 13
Output 2:
[10, 2]
