A13124 | Remove One Element

You are given an array $a$ consisting of $n$ integers.

You can remove at most one element from this array. Thus, the final length of the array is $n-1$ or $n$ .

Your task is to calculate the maximum possible length of the strictly increasing contiguous subarray of the remaining array.

Recall that the contiguous subarray $a$ with indices from $l$ to $r$ is $a[l \dots r] = a_l, a_{l + 1}, \dots, a_r$ . The subarray $a[l \dots r]$ is called strictly increasing if $a_l < a_{l+1} < \dots < a_r$ .

The first line of the input contains one integer $n$ ( $2 \le n \le 2 \cdot 10^5$ ) — the number of elements in $a$ .

The second line of the input contains $n$ integers $a_1, a_2, \dots, a_n$ ( $1 \le a_i \le 10^9$ ), where $a_i$ is the $i$ -th element of $a$ .

Print one integer — the maximum possible length of the strictly increasing contiguous subarray of the array $a$ after removing at most one element.
