Given an array of distinct integers arr , find all pairs of elements with the minimum absolute difference of any two elements.
Leverage Array / General with Array to process inputs efficiently and achieve optimal time and space complexity.
We iterate through the input using In-Place Array Traversal & Index Mapping. By maintaining state efficiently in a Array, we eliminate redundant operations and process each element in optimal time.
- 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 Minimum Absolute Difference. Applying In-Place Array Traversal & Index Mapping yields the target result step by step.
- Time Complexity: O(n)
