Problem 6

Suppose that a "mirror" section in an array is a group of contiguous elements such that somewhere in the array, the same group appears in reverse order. For example, the largest mirror section in {1,2,3,8,9,3,2,1} is length 3 (the (1,2,3) part). Display the size of the largest mirror section found in the given array.

Sample Test Cases:
maxMirror(1,2,3,8,9,3,2,1)=3
maxMirror(1,2,1,4)=3
maxMirror(7,1,2,9,7,2,1)=2
