QUESTION
I am looking at a query from crystal reports and it shows a table name immediately followed by a table name. see below if that didn't make sense but I am trying to understand what this syntax is/does? thank you in advance for any insight
...ANSWER
Answered 2022-Apr-01 at 19:24The 2nd name is the alias. It allows you to refer to the table using a different name. For example, you may want to shorten the references to that table throughout the rest of the statement in order to make things more readable. Or, more importantly, you may want to use the same table twice in the same statement (in which case an alias is required).
QUESTION
I am solving a problem on leetcode OJ where i had to use a custom comparator for set in C++.
...ANSWER
Answered 2022-Mar-19 at 07:18By adding that const
to the end of that member function you're making it a const member function, meaning that it cannot possibly modify any of your member variables. Because calling a non-const member function could modify the object, you can't call it if the object is const.
std::set
's erase member function requires that operator() be const to stop it from modifying the object's in their set without you realizing.
If any member function can be const then it should be const, just like any variables you declare or take in as arguments.
QUESTION
I am solving a problem on LeetCode:
Given an unsorted array of integers
nums
, return the length of the longest consecutive elements sequence. You must write an algorithm that runs inO(n)
time. So fornums
=[100,4,200,1,3,2]
, the output is4
.
The Union Find solution to solve this is as below:
...ANSWER
Answered 2022-Mar-14 at 07:33They are right. A properly implemented Union Find with path compression and union by rank has linear run time complexity as a whole, while any individual operation has an amortized constant run time complexity. The exact complexity of m
operations of any type is O(m * alpha(n))
where alpha
is the inverse Ackerman function. For any possible n
in the physical world, the inverse Ackerman function doesn't exceed 4. Thus, we can state that individual operations are constant and algorithm as a whole linear.
The key part for path compression in your code is here:
QUESTION
I am finalizing the representation of my dataset using ggplot2 and for the sake of clarity I would need a coloring scheme that defies standard ggplot2 "logic". Below is a fake dataset to show you my needs in essence:
...ANSWER
Answered 2022-Mar-12 at 13:01I would create a dummy
variable in your input df2
for the ggplot
fill
aesthetic. Here, "-999" refers to "OJ" and will be coloured in black.
I've also updated your myPalette
to include black in it, and also setNames
to it so that only "-999" will have a corresponding "black" value.

QUESTION
Here is are my menu items, and I want to filter only the Drinks in a drink Component, I am displaying both the 'Drinks' and 'Eat' under categories. And my goal is to only filter and extract the 'Drinks' as I am displaying the drinks on its own component.
Here is my data:
...ANSWER
Answered 2022-Jan-24 at 00:01MenuItems.filter((item) => "Drinks")
return always true
What you should be doing is comparing the category to drinks.
MenuItems.filter((item) => item.category === "Drinks")

QUESTION
I'm running macOS 11.6,LibreOffice 7.2.2.2,HSQLDB (my understanding is this is v.1.8, but don't know how to verify)
I'm a newbie to SQL, and I'm trying to write a DB to maintain a club membership roster. I'm trying to find everyone in the DB to whom renewal letters should be sent. The quirk is, if a person has never paid in the past, they should be sent a renewal letter. Old members who haven't renewed recently don't get a renewal, and obviously, each individual should only get one letter. I've created a toy example to display the problem I'm having...

QUESTION
Morning, I have a little problem with my ggplot
graph.
For some reason, I can't see right now, the y axis ticks and numbers are missing. Maybe, I'm missing something really obvious here or it's something in my settings.
The toothgrowth dataset does not really fit the graph, but you can still see the problem (normally facet_wrap
is included, but it does not work with this dataset).
ANSWER
Answered 2021-Dec-15 at 08:43Shouldn't your y axis be continuous?
