冒泡排序示例，雙向冒泡排序與對雙向冒泡排序稍微的改進(jìn)的可視化效果。
代碼很簡單，不知道有木有未知bug。
冒泡排序示例
var ls=[ 98,13,6,25,38,36,30,44,38,80,61,28,47,34,95,18,85,58,89,85,42,61,74,35,13,14,80,7,10,44,10,47,13,11,52,25,24,48,34,12,88,80,33,8,80,45,64,52,79,77 ];
for(var i=0;i<ls.length;i++){
for(var j=i+1;j<ls.length;j++){
if(ls[i]>ls[j]){
ls[i]=ls[i]+ls[j];
ls[j]=ls[i]-ls[j];
ls[i]=ls[i]-ls[j];
}
}
}
雙向冒泡排序示例
var ls=[ 6,13,98,25,38,36,30,44,38,80,61,28,47,34,95,18,85,58,89,85,42,61,74,35,13,14,80,7,10,44,10,47,13,11,52,25,24,48,34,12,88,80,33,8,80,45,64,52,79,77 ];
for(var i=0;i<ls.length;i++){
for(var j=i+1;j<ls.length-i;j++){
if(ls[lent-1-i]<ls[lent-j]){
ls[lent-1-i]=ls[lent-1-i]+ls[lent-j];
ls[lent-j]=ls[lent-1-i]-ls[lent-j];
ls[lent-1-i]=ls[lent-1-i]-ls[lent-j];
}//后面的比較
if(ls[i]>ls[j]){
ls[i]=ls[i]+ls[j];
ls[j]=ls[i]-ls[j];
ls[i]=ls[i]-ls[j];
}//前面的比較
}
}
雙向冒泡排序稍微改進(jìn)示例
var ls=[ 98,13,6,25,38,36,30,44,38,80,61,28,47,34,95,18,85,58,89,85,42,61,74,35,13,14,80,7,10,44,10,47,13,11,52,25,24,48,34,12,88,80,33,8,80,45,64,52,79,77 ];

ls[i*2]=ls[i*2]+ls[j+1];
ls[j+1]=ls[i*2]-ls[j+1];
ls[i*2]=ls[i*2]-ls[j+1];
}//保持內(nèi)層第一個數(shù)為循環(huán)最小
