数组中先前数字的总和 [英] Sum of previous numbers in an array
问题描述
我有一系列日期[30,30,31,31,30,30]，我需要把它写成[30,60,91,122,152,182]
我尝试过：
I have an array of dates [30,30,31,31,30,30] and i need to write it as [30,60,91,122,152,182]
What I have tried:
var dateArr = getDateArray(date2, date1);
var dayCounts = "";
for (var x = 0; x < dateArr.length-1; x++)
{
dayCounts += daysBetween(dateArr[x], dateArr[x+1]);
}
}

Tale一张纸，一支铅笔，用手解决问题。
你是如何解决的？这是你的算法。
你需要一些'日期'功能来得到答案吗？
HomeWork问题是那种简化版本你必须在现实生活中解决的问题，目的是学习和练习。
我们不做你的HomeWork。
HomeWork不会测试你乞求别人做你的工作的技能，它会让你思考和帮助您的老师会检查您对所学课程的理解以及您应用这些课程时遇到的问题。
你的任何失败都会帮助你的老师发现你的弱点并设定补救措施。
你的任何失败都会帮助你了解什么有效，什么无效，被称为'试错'学习。
所以，试一试，重读课程并开始工作。如果您遇到特定问题，请显示您的代码并解释这个问题，我们可能会提供帮助。
作为程序员，您的工作是创建算法解决特定问题，你不能依赖别人永远为你做，所以有一段时间你必须学会如何。而且越快越好。
当你要求解决方案时，就像试图通过培训其他人来学习开车一样。
创建算法基本上是找到数学并做出必要的调整以适应你的实际问题。
发展的概念就像这个词所暗示的那样：系统地使用科学和满足特定目标或要求的技术知识。 BusinessDictionary.com [ ^ ]
这与有一个不一样快速谷歌并放弃，如果我找不到正确的代码。
Tale a sheet of paper, a pencil and solve the problem by hand.
How did you solve it ? It is your algorithm.
Have you needed some 'date' function to get the answer ?
HomeWork problems are simplified versions of the kind of problems you will have to solve in real life, their purpose is learning and practicing.
We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.
The idea of "development" is as the word suggests: "The systematic use of scientific and technical knowledge to meet specific objectives or requirements." BusinessDictionary.com[^]
That's not the same thing as "have a quick google and give up if I can't find exactly the right code".
