ISC Computer Science Practical Paper - 2019 Question 2 Solved Write a program to declare a single dimensional array a[] and a square matrix b[][] of size N, where N>2 and N<10. import numpy as np from math import sqrt def square_matrix (*elements): size = sqrt (len (elements)) if size.is_integer (): return np.array (elements).reshape (int (size), int (size)) else: raise runtimeerror ("number of elements is not sufficient to make a square matrix") print (square_matrix (1, 2, 3, 4, 5, 6, 7, 8, 9)) # output: # Logic to find sum of lower triangular matrix. Let's first see what should be the step-by-step procedure of this program . * copy the non-boundary elements in a Create two empty arrays of size n. Add elements to both the array. Fig 1: A simple 4x4 matrix In order to represent this matrix in Java, we can use a 2 Dimensional Array. * To sort non-boundary elements of Matrix Now this program allows user to enter the dimension or size of 2D array and then its elements of given size to store it in a 2D array arr[][] and print the array back on output screen along with index number (row and column number starting from 0): The determinant of a matrix of order 2 2 is equal to the difference of the product of the diagonal elements of the matrix. A square matrix is a matrix which includes elements in the form of Rows and Columns. (Assume that the user will always enter only valid grades between 0 and 100 (or) 1.Also assume that the user will not enter more than 10 valid grades. To declare a two-dimensional integer array of size [x] [y], you would write something as follows type arrayName [ x ] [ y ]; Write a method that takes a parameter int size and returns an int[] array of that size. However, you can only take the square root of a square matrix. How does not, you use it can declare square matrix java and how to must purchase one direction. Out [1]=.
