USING JAVASCRIPT AND BUTTON ONCLICK IN THE BODY $-$ A magic square is a two$-$dimensional array of positive integers in which the fol$-$

lowing is true:

The number of rows equals the number of columns.

Every row, column, and the two diagonals add up to the same number.

Create a web page with a table that has four rows and four columns. Allow the

user to enter values for each cell. Store these values in a two$-$dimensional array

named magic and determine if it is a magic square.

Note: if we call the array magic then the sums of the two diagonals are as follows:

diagonal$2=$magic$[0][3]+$magic$[1][2]+$magic$[2][1]+$magic$[3][0]$;

Save the page with the filename magic. htm $1$ and submit your work as

instructed by your teacher.
