The document describes a Bubble_Sort program that sorts data into ascending and descending order. It generates random numbers and stores them in two arrays. It then uses bubble sort logic to sort one array in ascending order and the other in descending order by swapping elements that are out of order. Finally, it prints out the sorted arrays.

1. Program Buble_Sort;
USES Crt;
VAR
n, i, j,x, y : integer;
data,Data1,data2 : Array [1..50] of integer ;
BEGIN
clrscr;
randomize;
Write ('Masukkan banyak data : '); Readln (n);writeln;
write('Data Masukan : ');
For i:= 1 to n do
BEGIN
Data1[i]:=random(100);
Data2[i]:=data1[i];
Write(' ', Data1[i]);
End;
{Proses Mengurutkan Data Ascending}
For i:= 1 to n do
Begin
For j:= n downto i do
If Data1[i]>Data1[j] then
Begin
x:=Data1[i];
Data1[i]:=Data1[j];
Data1[j]:=x;

2. End;
End;
Writeln;
{Proses Mengurutkan Data Descending}
For i:= 1 to n do
Begin
For j:= n downto i do
If Data2[i]<Data2[j] then
Begin
y:=Data2[i]; {Simpan Data ke-i sbg bil Terkecil}
Data2[i]:=Data2[j]; {Tukar posisi Data}
Data2[j]:=y;
End;
End;
{Cetak Hasil Urutan Data Descending}
write('Data Ascending : ');
For i:= 1 to n do
Write(' ', Data1[i]);
writeln;
{Cetak Hasil Urutan Data Ascending}
write('Data Descending : ');
For i:= 1 to n do
Write (' ', Data2[i]);
readln;
END.
