System.arraycopy(elementData, index, elementData, index + 1, size - index); elementData[index] = element; size++; } 复制的部分越大,此操作就越慢。这使得添加元素的ArrayList操作效率相对较低。然而,到达应该完成插入的位置确实非常有效。 2.2LinkedList.add() LinkedList的实现允许我们相当容易...

Array(数组) 特征 1. 固定大小,数组的大小是初始化时决定无法修改的数值。 2. 强类型,存储数据元素类型必须在初始化时指定,因此在运行时,不需要耗费额外的时间来定义数组类型,能够大大提升运行效率。 3. 可使用Foreach关键字实现数组迭代和查找。 因为数组大小是固定的,且是强类型数据结构,因此在运行时只占用很少...

That also means that you can't delete an element or sort atuple. However, you could add new element to both list and tuple with the onlydifference that you will change id of the tuple by adding element(tuple是不可更改的数据类型,这也意味着你不能去删除tuple中的元素或者是对tuple进行排序,...
仅仅调用了 cl-set-difference 而已 (cl-set-exclusive-or LIST1 LIST2 [K V]...) ,对两者进行异或操作,即返回包含仅在 LIST1 或 LIST2 中出现的 ITEM 的新表 若其中一表为 nil 则返回另一表,若两表是 equal 关系则返回 nil 关键字参数有 :test :test-not :key 使用了 cl-set-difference ...
Hey Rico. I ran F1 on this scenario and I got some more data. But to be honest I'm still not 100% sure what these JIT_IsInstanceOfArray and ArrayIsInstanceOfNoGC function are doing in the array case. I have some guesses, but nothing that I'm sure of. Anyways, my run of th...
