{
For (int n = 0; n < ary.length; n++)
For (int k = n; k < ary.length; k++)
If (ary[n] > ary[k])
{
Float x = ary[n];
Ary[n] = ary[k];
Ary[k] = x;
}
}
B) void arrange(float[] ary)
{
For (int n = 0; n < ary.length; n++)
For (int k = n; k < ary.length; k++)
If (ary[n] < ary[k])
{
Float x = ary[n];
Ary[n] = ary[k];
Ary[k] = x;
}
}
C) void arrange(float[] ary)
{
For (int n = 1; n <= ary.length; n++)
For (int k = n; k < ary.length; k++)
If (ary[n] > ary[k])
{
Float x = ary[n];
