Found the solution.

PHP pack() packs the data into Binary string by taking format parameter.

As I am using "I" -> unsigned integer in pack() give result of 32bit encoding. Then trim() removes extra spaces and resulting data become encoding of below 8bit.

I've tried to generate a single-byte string from a number by using chr() in PHP

This doesn't have anything to do with nested functions. def sort_func(): defines a function that takes zero arguments, but key= expects a function that takes one argument. The error is simply due to that mismatch. The behavior would be identical if sort_func were a top-level, un-nested function like order.

def sort_func(sentence): fixed it because now sort_func accepts a single argument, which means it's usable as a key function.

You can simply create three variables and update their count based on the selected option.

If raw_input_file_list is a string, raw_input_file_list[x] is the xth character of that string.

What you might want to do is to use the split() method to split the string by commas into a list, and iterate through that list:

You should actually use Campaigns:

The algorithm provided only loops the array of words once. For what you stated your goal is to find the position of each word based on a number inside each word. There are several ways of solving this but I will explain an easy algorithm.

You can accomplish the desired result by creating a loop over the positions {1..N} and inside this loop another loop on the words {word1...wordN}. So for each position you will try to find what word belongs to that position. The following algorithm is one of many solution for this problem:

For the first one, it is easy:

As you have no doubt noticed, the Servlet spec does not allow you to read the Request body contents twice.

This is an intentional decision as any such feature would require caching or buffering the response body content. Which leads to:

• Various DoS / Denial of Service attacks against your webapp.
• Idle Timeouts on request processing when your code reads the request the second time from the buffer and produces no network traffic to reset the idle timeout.
• The inability to benefit from or use Servlet Async I/O processing.

JAX-RS endpoints typically require that the javax.servlet.http.HttpServletRequest input stream has not been read, at all, for any reason (*).

Your code makes no attempt to limit the size of the byte arrays you allocate, it would be easy to abuse your service with a Zip Bomb. (example: sending 42 kilobytes of data that unpacks to 3.99 petabytes)

You may find a JAX-RS implementation specific way, such as using Jersey internal code to set the entity stream, but that kind of code will be fragile and likely result in the need to fix your code and recompile with updates to your Jersey library.

If you go the custom route, please be take extra care to not introduce obvious vulnerabilities in your code, limit your request size, limit what you can buffer, etc.

Typically webapps that need to modify request input stream content do it via proxy servlets that perform middle-man modification of the request in real-time, on a buffer by buffer basis. Jetty has such a class, called conveniently AsyncMiddleManServlet. This essentially means your client talks to the proxy which talks to your endpoint, which honors network behaviors and network backpressure needs. (something a buffering filter wouldn't be able to handle properly)

(*) You can accidentally read the HttpServletRequest body by using things from the request that ask for the request parameters or the request parts (which require that the body content be read for certain specific Content-Types)
