## 题目

You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list.

You may assume the two numbers do not contain any leading zero, except the number 0 itself.

## 题目

Given an array of integers, return indices of the two numbers such that they add up to a specific target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

Example:

## white-space

CSS 属性 white-space 用于控制空白字符/换行符的显示方式.

normal(默认值)

## FunctionDeclarationInstantiation

ECMAScript® 2018 Language Specification

When an execution context is established for evaluating an ECMAScript function a new function Environment Record is created and bindings for each formal parameter are instantiated in that Environment Record.Each declaration in the function body is also instantiated.

If the function's formal parameters do not include any default value initializers then the body declarations are instantiated in the same Environment Record as the parameters. If default value parameter initializers exist, a second Environment Record is created for the body declarations.

Formal parameters and functions are initialized as part of FunctionDeclarationInstantiation. All other bindings are initialized during evaluation of the function body.

FunctionDeclarationInstantiation is performed as follows using arguments func and argumentsList. func is the function object for which the execution context is being established.
FunctionDeclarationInstantiation 使用 func 和 argumentsList 作为参数,依照如下步骤执行.func 是为其建立execution context (函数 执行环境/上下文)的对象, arguments 是调用函数时传递的参数(实参列表).
