My Solution :

#!/usr/bin/env python3

def minimumAbsoluteDifference(n, arr):
    arr = sorted(arr)
    ret = arr[1] - arr[0]
    for i in range(1, n-1):
        ret = min(ret, arr[i+1] - arr[i])
    return ret


n = int(input())
arr = list(map(int, input().strip().split()))
result = minimumAbsoluteDifference(n, arr)
print(result)
