Solve the Split Array problem focusing on prefix sums, array partitioning, and efficient counting, typically resolved using a binary search on the answer approach.
Design and implement a Time-Based Key-Value Store using Binary Search. Discuss the time and space complexity of the proposed solution.
Given a binary matrix, identify the row that has the maximum number of 1s. The initial approach involves applying binary search on every row with a time complexity of O(m log n). An optimized solution starts from the top-right corner of the matrix. If the current value is 1, move left; if 0, move down. Keep track of the row whenever moving left. The final time complexity is O(m + n) and space complexity is O(1).
