Question
A.Write a looping structure (using java- 100X100 array) to process the elements on the main diagonal of a (i.e. only the elements on the diagonal starting from the top left and proceeding to thebottom right).
B.Write a looping structureusing( java- 100X100 array) to process the elements on the back diagonal of a (i.e. from top right to bottom left).
C.Write a looping structureusing( java- 100X100 array) to process the elements in the lower triangular portion of a (i.e. the first element in the first row, the first two elements in the second row,etc.)
D.Write a looping structure(using java- 100X100 array) to process the nine elements centered on (x,y) (i.e. (x,y) and the eight neighboring cells one row and/or column away from (x,y)).
Explanation / Answer
a)
for(int i=0;i<100;i++)
{
for(int j=0;j<100;j++)
{
System.out.print(" " +arr[i][j]);
}
System.out.println(" ");
}
System.out.println("Diagonal elements are: ");
for(int i=0;i<100;i++)
{
for(int j=0;j<100;j++)
{
if(i!=j)
System.out.print(" ");
else
System.out.println(" "+arr[i][j]);
}
}
}
}
b)
for(int i=100;i<100;i++)
{
for(int j=0;j<100;j++)
{
System.out.print(" " +arr[i][j]);
}
System.out.println(" ");
}
System.out.println("Diagonal elements are: ");
for(int i=0;i<100;i++)
{
for(int j=99;j>=0;j--)
{
if(i!=j)
System.out.print(" ");
else
System.out.println(" "+arr[i][j]);
}
}
}
}
