Minimum Operations to Form Stepwise Pattern

Problem Statement

Minimum Operations to Form Stepwise Pattern Problem Description You are managing a row of building structures with varying heights represented by an array structures . You want to transform these structures into a harmonious pattern where each structure differs from its adjacent neighbors by exactly one unit in height, forming either an ascending or descending sequence. To modify the structures, you can only add one unit of height to any structure in a single operation. Your goal is to determine the minimum number of operations needed to achieve either an ascending or descending stepwise pattern - whichever requires fewer operations. Examples Example 1: Input: structures = [1, 4, 3, 2] Output: 4 Explanation: The optimal approach is to add: Four units to the first structure. The final heights will be: [5, 4, 3, 2] , forming a descending stepwise pattern. Example 2: Input: structures = [5, 7, 9, 4, 11] Output: 9 Explanation: The optimal approach is to add: Two units to the first structur
