{

Scanner sc = new Scanner ( System.in);

int i , j , t = 0;

S.o.pln ( "enter 20 no.");

int a [ ] = new int [20]

for (i=0;i<=19 ;i++)

{

a[ i ] = sc.nextint( ) ;

}

for (i=0;i<=18;i++)

{

for ( j=0;j<=18;j++)

{

if (a[j] < a[ j+i] )

{

t=a[j] ;

a[j ] = a [j+1] ;

a[j+1] = t ;

}

}

}

S.o.pln ( "descending order ");

for (i = 0 ; i<=19 ; i++)

{

S.o.pln ( a[i] ) ;

}
