Master this problem using the Shortest Path pattern.
When approaching Path With Minimum Effort, look for key problem signals that suggest using the Shortest Path pattern. Focus on reducing redundant iterations, maintaining state invariant, and optimizing space-time complexity.
Key Invariant
Maintain optimal range bounds or hash frequency state during traversal.
Expected Complexity
Time: O(N) or O(N log N) | Space: O(1) to O(N)
