An efficient solution is also the same as in the naive approach but in this, we are taking only one loop to find the diagonal element and then we print the square of that element. 1.

WebFeb 16, 2024 · Approach: From the diagram it can be seen that every element is either printed diagonally upward or diagonally downward. Start from the index (0,0) and print the elements diagonally upward then change the direction, change the column and print diagonally downwards. This cycle continues until the last element is reached.
