I know there is functions and probably easier to locate if there is matching matrix inside a larger matrix. I want to locate matrix M, inside matrix A. How can i set up the for loops since both matrix are different size? A,6x6 matrix A= [8 2 9 7 6 7; 9 5 4 1 7 0;

One simple solution is to scan the whole 2D array for the key in O (mn) time. However, there are better solutions with less time complexity that use the sorted property of matrix. We can use a binary search on each row to find if the key exists in a row or not. The time complexity of this solution is O (m * log n).
