Before learning bubble algorithm, always do not know the relationship between N and N-1, and other variables, the reason is not to understand its true meaning, today wrote a bubble algorithm of the JS applet, and finally figured out.
var r1=new Array ();
r1[1]=35;
r1[2]=55;
r1[3]=65;
r1[4]=20;
r1[5]=30;
r1[6]=25;
r1[7]=0;
r1[8]=7;
r1[9]=5;
r1[10]=3;
var r2=new Array (35,55,65,20,30,25,0,7,5,3);
var r3=new Array (35,55,65,20,30,25,0,7,5,3);

function BubbleSort1 ()
{
var n=r1.length-1;
for (Var i=1;i<n;i++)
{
var Flag=false;
for (Var j=n-1;j>=i;j--)
{
var temp;
if (R1[j+1]<r1[j])
{
TEMP=R1[J+1];
R1[J+1]=R1[J];
R1[j]=temp;
}
Flag=true;
}
if (!flag) return;
}
}

function BubbleSort2 ()
{
var n=r2.length;
for (Var i=0;i<n-1;i++)
{
var Flag=false;
for (Var j=n-2;j>=i;j--)
{
var temp;
if (R2[j+1]<r2[j])
{
TEMP=R2[J+1];
R2[J+1]=R2[J];
R2[j]=temp;
}
Flag=true;
}
if (!flag) return;
}
}
function BubbleSort3 ()
{
var n=r3.length;
for (Var i=0;i<n-1;i++)
{
var Flag=false;
for (Var j=n-1;j>i;j--)
{
var temp;
if (R3[j]<r3[j-1])
{
TEMP=R3[J];
R3[J]=R3[J-1];
R3[j-1]=temp;
}
Flag=true;
}
if (!flag) return;
}
