Question 1: Magic Matrix Magic square is an ? × ? matrix that is filled with the numbers 1,2,3, . . . . . , ?2 is a magic square if the sum of the elements in each row, in each column, and in the two diagonals is the same value. 6 1 8 7 5 3 2 9 4 Write a Java code to randomly generate a 3X3 matrix and check if the matrix is the magic square. In your code you must test two features: a. Does each of the numbers 1,2,3,….9 occur in the matrix? b. Are the sums of the rows, columns, and diagonals equal to each other? Note: to generate a random number use the method Math.random() which generates a pseudo random number greater than or equal to 0 and less than 1. Sample Output could be as follows: Sample 1: The randomly generated matrix is: 4 3 8 9 5 1 2 7 6 Sample 2: The randomly generated matrix is: 4 9 2 3 5 7 8 1 6
To simulate the game detailed above in a computer environment as a C ++ con sole application, follow the steps below in order: Declare a two-dimen sional array of 10 rows and 15 columns that can store integers in the int data type. Each row of this tw o-dimensional array represents a tombala card. Therefore, this series has the capacity to store 10 different tombala cards. Assign 15 unique random integers in the range of 1 (inclusive) to 90 (inclusive) to each row of this array. Prototype for this purpose void CreateCards (int[][15], int); Make use of the sub-function given in the form. The first parameter of this function is the two-dimensional array that stores tombala cards, and the second parameter is the total number of cards. Then print the contents of the series on the screen similar to the following output TOMBALA KARTLARI HAZIRLANIYOR=TOMBALA CARDS ARE PREPARING
