WebWe can do a binary search to find an index of the first occurrence and the last occurrence of the given key for each row. The complexity of this solution will be O (M × log (N)), which is not linear as per problem time constraints. The idea is to take advantage of the fact that the matrix is row-wise and column-wise sorted. WebJul 18, 2024 · First, a function accepts four inputs: the first index, last index, list, and to_search (item to be searched). Then we check if the value of the last index is greater than or equal to the value of the first index. If the condition is true, we assign the operation of finding the middle element index to the variable name "mid_index". china and india relationship https://i2inspire.org
