find a specific pair in matrix leetcode

For all values mat(a, b) in the matrix, we find mat(c, d) that has maximum value such that c > a and d > b and keeps on updating maximum value found so far. A row and column pair is considered equal if they contain the same elements in the same order (i.e. The output will be 18. Time complexity: O(N4).Auxiliary Space: O(1), The above program runs in O(n^4) time which is nowhere close to expected time complexity of O(n^2). 373. Given an array of integers nums and an integer k, return the number of unique k-diff pairs in the array. For space complexity, the queue will use O(mn) extra space. Time complexity: O (N4). The steps are: (1) building a graph where the index are the node number, and the graph[i] would be a list of elements (could be other_node or a . expected time complexity is O(n 2) A simple solution would be to apply Brute-Force.
