A) 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;
}
}
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];
Ary[n] = ary[k];
Ary[k] = x;
}
}
D) 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])
