Provide tags and a correct Python 3 solution for this coding contest problem.
This problem is given in two editions, which differ exclusively in the constraints on the number n.
You are given an array of integers a[1], a[2], ..., a[n]. A block is a sequence of contiguous (consecutive) elements a[l], a[l+1], ..., a[r]... | instruction | 0 | 7,615 | 12 | 15,230 |

Correct Solution:
```
