## Lunatic Never Content Solution Codeforces

You have an array a� of n� non-negative integers. Let’s define f(a,x)=[a1modx,a2modx,…,anmodx]�(�,�)=[�1mod�,�2mod�,…,��mod�] for some positive integer x�. Find the biggest x�, such that f(a,x)�(�,�) is a palindrome. Here, amodx�mod� is the remainder of the integer division of a� by x�. An array is a palindrome if it reads the same backward as forward. More formally, an array a� of length n� is a palindrome if for every i� (1≤i≤n1≤�≤�) ai=an−i+1��=��−�+1. Lunatic Never Content Solution Codeforces The first … Read more
