AT_abc396_a [ABC396A] Triple Four

You are given an integer sequence of length $ N $ : $ A = (A_1,A_2,\ldots,A_N) $ . Determine whether there is a place in $ A $ where the same element appears three or more times in a row. More formally, determine whether there exists an integer $ i $ with $ 1 \le i \le N-2 $ such that $ A_i = A_{i+1} = A_{i+2} $ .

The input is given from Standard Input in the following format: > $ N $ $ A_1 $ $ A_2 $ $ \ldots $ $ A_N $

If there is a place in $ A $ where the same element appears three or more times in a row, print `Yes`. Otherwise, print `No`.

### Sample Explanation 1 We have $ A=(1,4,4,4,2) $ . There is a place where $ 4 $ appears three times in a row, so print `Yes`. ### Sample Explanation 2 We have $ A=(2,4,4,2,2,4) $ . There is no place where the same element appears three or more times in a row, so print `No`. ### Constraints - $ 3 \le N \le 100 $ - $ 1 \le A_i \le 100 $ - All input values are integers.
