You are given an integer array nums and an integer k.

An integer is considered almost missing if it appears in exactly $1$ contiguous subarray of nums of size k.

Return the largest almost missing integer. If no such integer exists, return $-1$.

Constraints:

• $1 \leq$ nums.length $\leq 50$

• $0 \leq$ nums[i] $\leq 50$

• $1 \leq$ k $\leq$ nums.length
