K Increment Palindrome
Chef has an array $A$ of size $N$ and an integer $K$. He can perform the following operation on $A$ any number of times: - Select any $K$ distinct indices $i_1, i_2, \ldots, i_K$ and increment the array elements at these $K$ indices by $1$. Formally, set $A_{i_j} := A_{i_j} + 1$ for all $1 \le j \le K$. For example, if $A = [3, 2, 8, 4, 6]$ and we select the indices $2, 3, 5$, then $A$ becomes
