Expected Auxiliary Space: O(N^2) So, unlike standard DFS(), where we recursively call for all adjacent vertices, here we can recursive call for 8 neighbours only. 3 4 The basic condition to apply Binary Search anywhere in any algorithm is that the search space should be sorted. The same letter cell may not be used more than once. #while-loops Constraints: Complete the function sumMatrix() that takes A and B as input parameters and returns a matrix containing their sum. static int findMinOperation(int matrix[] [], int n) { n2 = 3, m2 = 2 A beautiful matrix is a matrix in which the sum of elements in each row and column is equal.
