kandi X-RAY | radix Summary
This package is an implementation of a radix tree in Go (or Golang). Searching for static values in the tree doesn't allocate memory on the heap, what makes it pretty fast. It can also sort nodes by priority, therefore traversing nodes that hold more non-nil values first.

I am trying to perform a circular shift in Swift and I currently have the following code which uses a string containing the bits of the number I am trying to perform the circular shift on. Here is the code I have so far,
...ANSWER
Answered 2021-May-28 at 21:21You can achieve this with two bit shift operators and a bitwise OR:
QUESTION
I'm trying to implement a 32bits checksum macro written in masm32 to the Dart language. Here is what I understood: the checksum function takes a String as input and returns the checksum in a 4 bytes integer. But I don't get the same result. Does anyone see my errors please?
...ANSWER
Answered 2021-May-23 at 18:20The transcription of the checksum algorithm is wrong.
Here's how I'd do it:

...ANSWER
Answered 2021-May-20 at 22:08The error is misleading. The problem doesn't have to do with the 3001
portion, instead Uri.http
is expecting the base_url to be more, well, basic.
Changing the code to this resolved the problem:
QUESTION
Let's say that you are given an integer array A
of size n
. You know in advance that O(√n)
elements of A
can be larger than 2020(n)^(5) − 5n
, and the remaining elements of A are in the range [1, 2020n^5 − 5n]
. It turns out that, in this case, A
can be sorted in O(n)
time in the worst case.
I am trying to solve this interesting algorithm question and my intuition is to use radix sort as part of my solution. The part that stumps me is the O(√n)
runtime, so any pointers in finding such an algorithm would be greatly appreciated!
ANSWER
Answered 2021-May-05 at 17:06Separate the in-range elements from the out-of-range elements (O(n)). Radix sort in the in-range elements (base n; this takes six passes for n ≥ 2020 and is O(n)). Insertion sort the out-of-range elements (there are √n of these, hence O(√n²) = O(n)). Merge the two sorted arrays (O(n)).

constructor.

QUESTION
I am reviewing a function to generate keys for a Radix Map and found the implementation of rand() to be novel to me.
Here is the function:
...ANSWER
Answered 2021-Apr-27 at 01:39The C standard only guarantees that RAND_MAX
is at least 32767. This code accounts for that by calling rand
twice and shifting to ensure it gets at least 30 bits of randomness.
However, this does does not properly account for the case where RAND_MAX
is larger.
The rand
function returns an int
which is signed. If RAND_MAX
was the same as INT_MAX
, rand() << 16
would most likely shift a "1" bit into the sign bit, triggering undefined behavior.
The proper way to implement this to handle both cases is:
QUESTION
IEEE 754-2008:
7.5 Underflow
The underflow exception shall be signaled when a tiny non-zero result is detected. For binary formats, this shall be either:
a) after rounding — when a non-zero result computed as though the exponent range were unbounded would lie strictly between ±bemin, or
b) before rounding — when a non-zero result computed as though both the exponent range and the precision were unbounded would lie strictly between ±bemin.
The implementer shall choose how tininess is detected, but shall detect tininess in the same way for all operations in radix two, including conversion operations under a binary rounding attribute.
However, both C11 and C17..C2x (working draft — February 5, 2020, n2479.pdf
) say nothing about tininess:
ANSWER
Answered 2021-Apr-22 at 00:20The following program may determine whether tininess is reported before or after rounding.
QUESTION
Following Swift Standard Library documentation, &+
discards any bits that overflow the fixed width of the integer type. I just did not get why adding two maximum values, 8-bit signed integer can hold results in -2:
ANSWER
Answered 2021-Apr-19 at 05:47Swift (and every other programming language I know) uses 2's complement to represent signed integers, rather than sign-and-magnitude as you seem to assume.
In the 2's complement representation, the leftmost 1
does not represent "a negative sign". You can think of it as representing -128, so the Int8
value of -2 would be represented as 1111 1110 (-128 + 64 + 32 + 16 + 8 + 4 + 2).
OTOH, -126 would be represented as 1000 0010 (-128 + 2).
