Given two Arrays, A and B, write a C++ function to check if B is a rotation of A. B is a rotation of A iff the elements of B are the same elements of A after being shifted left n times for any integer n.

For example: if A={1, 2, 3, 4} and B={3, 4, 1, 2} then the function will return true because the elements of B are the same as A after being shifted left twice.

Note: You must use the following header:

bool isRotation(int arr1[],int arr2[]);
