推荐答案
我只是看第一个练习 - sumNumbers。你的代码似乎是随机的，就像你从之前的练习中复制它一样。首先，您将字母和数字复制到第二个字符串（为什么？）并且对结果字符串不执行任何操作，然后您似乎在对原始字符串中的数字进行求和。看看其中一个例子：
sumNumbers（" aa11b33"）→44
如果你将数字相加它将是1 + 1 + 3 + 3 = 8，而不是11 + 33 = 44.
我建议你从伪代码开始 - 你如何用简单的步骤描述这个操作的解决方案？
I''m just looking at the first exercise -- sumNumbers. your code seems rather random, like you copied it from an earlier exercise. First you copy letters and digits to a second string (why?) and do nothing with the resulting string, then you seem to be summing up the digits in the original string. Take a look at one of the examples:
sumNumbers("aa11b33") → 44
If you summed the digits it would be 1 + 1 + 3 + 3 = 8, not 11 + 33 = 44.
I suggest you start with pseudo code -- how you you describe the solution to this operation in simple steps?

是的，我忘了把ret字符串放在另一种方法中。对于像7 11这样的字符串，它有一个空格，所以我想压缩它。是的，我明白你的意思。
首先，我会检查每个字符，看看它是否是一个int。然后我必须做一些事情，检查它是否是一个两位数或一位数，我在那里遇到麻烦
yeah, i forgot to put ret string in the other method. For a string like "7 11", it has a space in it, so I want to condense it. Yeah, i see what u mean.
First I would check each char and see whether or not it is a int. then i have to do something ot check whether or not it is a double digit or a single digit, im having some trouble there

三位数，四位数，... 。Hello123World4567Example
一直在考虑它，直到你提出的解决方案对你更清楚。
Triple digits, quadruple digits, ... "Hello123World4567Example"
keep thinking about it until your proposed solution is clearer to you.
