kandi X-RAY | judge Summary
Judge allows easy client side form validation for Rails by porting many ActiveModel::Validation features to JavaScript. The most common validations work through JSON strings stored within HTML5 data attributes and are executed purely on the client side. Wherever you need to, Judge provides a simple interface for AJAX validations too.

QUESTION
This is a part of code in an arduino SPI communication instance.
...ANSWER
Answered 2021-Jun-09 at 19:14Before explaining, you have to understand a few things:
- Characters (i.e., a
chartype) can be treated as a number without any cast based upon its ASCII encoding - Strings in C always end with a NUL terminator. Importantly, this character has a numerical value of 0 (i.e., when you treat it as a number, it's equal to zero).
- Boolean values don't really exist in C independant of an integer representation. Zero is treated as "false" and anything else is treated as "true".
With this out of the way, let's look at what's happening in the loop.
First, we have a pointer p that points at the first character of the string "Hello world!\n" (this is coming from the statement const char* p = "Hello, world!\n").
At the top of the loop, we check our loop condition, which is c = *p. Note that this assigns the value pointed at by p into c, and assignments in C evaluate to the value that's been assigned. What that means in this context is that our test is essentially just *p.
Since booleans don't exist in C, *p is false only when the character pointed at by p has a value of zero. This can only happen when p is pointing to a NUL terminator, which is always at the end of a string in C. Therefore, our loop will stop when we've hit the end of our string.

In Kotlin, the type system distinguishes between references that can hold null (nullable references) and those that cannot (non-null references). For example, a regular variable of type String cannot hold null:

I guess that the data structure used is not appropriate, but I have thought about it for a long time and I don't know where to adopt a good data structure, please give me some advice.
algorithm ideas:
This approach is somewhat similar to selection sort. First, find a lucky number, then swap the position with the first number, then start from the second, find the smallest number, and then swap it with the lucky number, so that the smallest number starting from the second is placed at the first position, the lucky number is now in another position, and its position is recorded. Then swap the lucky number with the second number, and then repeat the above process. Special attention should be paid to the fact that we need to record the position of the lucky number we selected after sorting because the process before and after the position is slightly different and needs to be compared(This is explained in the code comments).

So here we are packing objects and Both Length, Width and Height of object should be less than 50 for a good case and if any is more than 50 then the case is bad. I have written my program below but all cases are judged by the last case.

Sample output
Case 1: good
Case 2: bad

Answered 2021-May-27 at 15:50If your problem is that all cases are judged by the properties of the last case (though, as has been noted, it is not clear what this means for the results of your code as given), then it could be because when case is assigned in:

Answered 2021-May-21 at 17:17Unfortunately, you basically have to draw the outline manually with a bunch of points, just the way you've done so far (there are ways to do it automatically, but the only ones I know of require some pretty advanced techniques). Here's some code that might help you figure out where to draw the points:
