算法筆記(1) ——插入算法

var ary = [5, 2, 4, 6, 1, 3,31,4,0,1,43];
function InsertionSort(){
    for (var j = 1; j < ary.length; j++) {
        var key = ary[j];
        var i = j - 1;

        while(i >= 0 && ary[i] > key){
           ary[i + 1] = ary[i];
           i--;
        }
        ary[i + 1] = key;
    };
}
