Streak Star

The **Streak Value** of an array $B$ is defined as the maximum length of a non-decreasing subarray, more formally: $$ \max_{1 \leq i \leq j \leq N} (j - i + 1) \quad \text{where} \quad B_i \leq B_{i+1} \leq B_{i+2} \leq \dots \leq B_j. $$ Chef has an array $A$ of length $N$ and a magical number $X$. You are allowed to perform the following operation at most once: - Select an index $i$, and u
