Minimize the maximum partition sum. - Find the smallest missing positive integer in O(n) time and O(1) space. - Maximum subarray sum after deleting at most one element. - Given heights of buildings, find how much rainwater can be trapped in 2D. - Minimize operations to make all array elements equal where one operation increments a subarray. - Find the kth smallest pair distance among all pairs. - You have infinite coins of powers of 2. Count ways to form N with exactly K coins. - Find the longest subarray where GCD of all elements > 1 - Streaming version: Numbers arrive continuously. Maintain median, kth largest, and percentile queries simultaneously. 1/n Practice portal where you can solve these: geeksforgeeks.org/explore?page=1…
