QUESTION
I want to build a key-value container to save data.
i can build a three-level unordered_map to map it, the key will be >>, but i think it's slow.
So, I want to map into a unique int. then i can save it in one-level unordered_map
For example:
assume the three key is called a, b, c, a's range is [0, 1e4], b [0, 1e6] c [0, 1e5]
i want to wirte a function like this:
...ANSWER
Answered 2021-Jun-15 at 03:26unordered_map expects a hash function returning size_t, so if you're compiling a 64-bit application (as most people do except in some embedded environments), you can combine the integers trivially:

I'm writing a form which contains all days of the week, but theses days are save in an int field $days. I'm using bitwise-op to display the selected days.
...ANSWER
Answered 2021-Jun-14 at 08:52For your case you can create a custom "Form Field Type" (and maybe if needed a custom Data Transformer) and customize also the form template as described in the docs.
For example:

with open("image.jpg",'rb') as file:
file.seek(163)
a = file.read(2)
height = (a[0] << 8) - a[1]

width = (a[0] << 8) - a[1]
print(str(height) + " x " + str(width))

QUESTION
In TTN they are no longer supporting large decoders.
I know what the decoder needs to be in TTN, it is in my DECODER function, but dont know how to execute it in the function node.
If you use inject Payload [1,2,3] RAW, it injects the raw payload that is msg.payload.payload.uplink_message.frm_payload into the decoder.
The DECODER needs to decode the raw payload and output it in msg.payload.uplink_message.decoded_payload
If you use inject Payload [1,2,3] Decoded in the flow you see how the end result needs to look like and the decoded msg.payload.uplink_message.decoded_payload

The task at hand is to be able to return the bitwise AND and bitwise OR from a bitstring. Everything seems to be okay but my immediate problem has to do with calling my first function into the other two.
I tried solving changing the code and came up with different variable names but nothing changed the error seen in the terminal. I also tried if __name__ == __'main'__: but nothing has changed as well. I've been researching all day but still have not solved the issue. Here is my code:

Answered 2021-Jun-06 at 14:05Here's how to fix the problem you were having with the finalresult = OperationAND('10001', '11011') statement, which was to remove it from the class definition, as well has a few other bugs I encountered in the process of doing so.
Below is final result with # ALL CAP COMMENTS indicating everthing I changed (I think).
QUESTION
According to Wikipedia the js arithmetic shift right and left operators are << and >> and while the left shift seems to be working correctly, the right shift seems to be doing a bitwise shift rather than a arithmetic one
ANSWER
Answered 2021-Jun-03 at 21:54I'm not sure what values you are expecting. An arithmetic bit shift is what JavaScript does, but you will never see it without using negative values.
For example:
-1 >> 1 === -1
or
-20 >> 1 === -10
If these were standard logical bit shifts instead, the result would be dependent on the bit depth of the values, and not meaningful in the context of JavaScript. For example, the difference between logical and arithmetic bit shift in 8-bit (to keep it simple):
-1 would be 1111 1111:
1111 1111 arithmethic shift right = 1111 1111 (still -1, the high bit is "sticky")
1111 1111 logical shift right = 0111 1111 (now 127)
Edit: In JS, if you want to use a logical shift right, you can use >>> instead of >>. It works on 32-bit integers when you do. So:
-1 >>> 1 === 2147483647

Problem statement (link):
...ANSWER
Answered 2021-Jun-02 at 04:53There are some issues with this implementation. start and end should remain iterators, they could be used directly without adding/subtracting nums.begin() all the time. We're talking about non-negative integers, so provided they fit into normal int first bit is 0 anyway, so we should start with int bit = 30 to skip one needless iteration. For integers right as for iterators as well, start <= end - 1 is better compared as start < end. The code consists of one single function, there's absolutely no need for a class then, so one should prefer a namespace. Applying these changes, the code would look like this:
