Master this problem using the Bitmask DP pattern.
When approaching Minimum Number of Work Sessions to Finish the Tasks, look for key problem signals that suggest using the Bitmask DP 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)
