You are given a 0-indexed array of distinct integers nums .
Leverage Array / General with Array to process inputs efficiently and achieve optimal time and space complexity.
Find indices of the min and max. Consider three strategies: remove both from the front, both from the back, or one from each end. Return the minimum deletions among all strategies.
- Initialize state variables / data structure (Array).
- Process elements sequentially using In-Place Array Traversal & Index Mapping.
- Validate boundary conditions and return optimal result.
Consider the standard input for Removing Minimum and Maximum From Array. Applying In-Place Array Traversal & Index Mapping yields the target result step by step.
- Time Complexity: O(n)
- Space Complexity: O(1)
Array / General
- Array
C++
By utilizing Array / General, each element is processed efficiently, ensuring optimal performance while avoiding unnecessary re-computations.
- Missing edge cases (empty inputs, boundary limits, negative values).
- Off-by-one errors in loop conditions.
- TLE due to suboptimal data structure choices.
- Tests: Fundamental DSA concepts, problem analysis, and edge-case handling.
- Follow-up: How would you scale this solution for large input streams?
