Question: Given a matrix that is sorted in row wise and column wise, find a number if present in the most efficient way. Input: Find if 54 is present in matrix. 4 8 15 16 23 6 9 20 21 44 8 11 24 26 49 9 13 25 27 54 10 17 29 30 66 Output: Present Method 1(Brute force):- Here, we use two loops search the element in entire matrix. Its a linear search so its not an efficient way to solve this problem. Time Complexity:- O(rows * …
