中文文档

Description

Write a function createHelloWorld. It should return a new function that always returns "Hello World".

 

Example 1:

Input: args = []
Output: "Hello World"
Explanation:
const f = createHelloWorld();
f(); // "Hello World"

The function returned by createHelloWorld should always return "Hello World".
