Wait a moment and try again. The main challenge with the problem is finding $$$cost(i) = \min\limits_{1 \leq j \leq n}(p_j + |i-j|)$$$ quickly, We can split the cost into two parts: $$$cost(i) = \min(p_j + (i - j))$$$ when $$$j \leq i$$$ and $$$cost(i) = \min(p_j + (j - i))$$$ when $$$j \geq i$$$, Combining them together, we get $$$cost(i) = \min(\min\limits_{1 \leq j \leq i} (p_j - j) + i, \min\limits_{i \leq j \leq n}(p_j + j) - i)$$$. Given q queries. Queries There's a "replace" function $$$f$$$ which takes a pair of integers $$$(l, r)$$$, where $$$l \le r$$$, as input and outputs the pair $$$$$$f\big( (l, r) \big)=\left(\min\{a_l,a_{l+1},\ldots,a_r\},\, \max\{a_l,a_{l+1},\ldots,a_r\}\right).$$$$$$.
