Mobile coding works. A laptop is faster for long sessions.
Problem
Read a positive natural number `n` followed by `n` integers forming
a sequence `v[1], v[2], ..., v[n]`. A run of equal values is a
contiguous portion of the sequence whose elements all share the same value.
Determine the length of the longest such run.
Input format
Input
input.txt
The first line contains `n`. The second line contains `n` integers separated by spaces. - `1 <= n <= 1000` - elements are integers in `[-10^9, 10^9]` - if there are several runs of maximum length, the length is unique
