Circular Shift

Write a function that takes two arrays (arr1 and arr2) and an int n, and returns true if the second array is equal to the first array shifted by n positions. Otherwise, return false.

Examples

circularShift([1, 2, 3, 4], [3, 4, 1, 2], 2) ➞ true

circularShift([1, 1], [1, 1], 6) ➞ true

circularShift([0, 1, 2, 3, 4, 5], [3, 4, 5, 2, 1, 0], 3) ➞ false

Notes

• The two arrays will be of the same length.
• n can be a negative value.
