...所以第一篇文章就从slice开始。 _.slice(array, [start=0], [end=array.length]) 这个函数的作用就是裁剪数组array,从start下标开始,到end下标结束,但是并不包含end,并将结果作为一个数组返回。并且注明了: Note: 这个方法用于代替 Arra...

... 一、直接插入排序 1. 单趟排序 x插入一个有序区间 这里end是指向数组最后一个元素 2. 直接插入排序 根据上面的单趟排序启发 end是数组的最后一个元素,end之后的元素都是待排序 一个关键的判断点,end和x比较大小 这里end < ...
...怎么实现的,我们可以实现单趟的排序,代码如下: int end = n-1;// 先定义一个变量将要插入的数保存起来int x = a[end + 1];while (end >= 0){ // 直到后面的数比前一个数大时就不往前移动,就直接把这个数放在end的后面 if (a[end] > x) { a[e...
