Random Input Problem

You are given a **randomly generated** permutation $P$ of length $N$. You can perform the following operation any number of times (including zero): - Choose an index $i$ such that $1 ≤ i $$ \begin{aligned} P_i &= \min(P_i, P_{i+1}) \quad and & P_{i+1} &= \min(P_i, P_{i+1}) \end{aligned} $$ In other words, replace both $P_i$ and $P_{i+1}$ with the smaller of the two values.
