If we display it in the same way as a 2D integer array we will get unnecessary garbage values in unoccupied spaces. If you pass k = -2, then it will return [6, 10] Construct Diagonal From NumPy Array. Let us see the steps. So what we are basically supposed to do is find the diagonals of an $r\times c$ matrix. Time complexity : O(n). The major diagonal is given through: 1 0 0. Inside this loop, another loop will run as well and it will print an asterisk as long as the current iteration index is lower than the parent loop iteration index. Following is a test-case of this program: Input: Enter the size of the square. If the pixel array is null or size 0, the call has no effect. The diagonals are of two kinds: The major diagonal and the minor diagonal. Here in this program, we will code to find out the sum of non-diagonal elements and separate them with elements above the diagonal and elements below the diagonal.
