Look for patterns and breaking down into methods
From the looks of it, you are trying to 'prettify' relative time representation given minutes, hours and days, such that negative values indicate the future and positive the past.
private static String getString(int minutes, int hours, int days)...
I've given the Rod-Cutting Problem a go with a non-recursive approach that use a cache instead, with a bottom up approach. For anyone who hasn't heard about the Rod-Cutting problem, it's defined as follows:
Serling Enterprises buys long steel rods and cuts them into shorter
rods, which it t...
I have some breadcrumbs that i use with Jquery, the problem is that i check if there is that element on page and after that i create element, but the problem it is getting to big and DOM is check so many times, that will slow my application. Now it work, but is there some simpler and better solut...
Below is the list abstraction in functional paradigm, that encapsulates any type of data in its representation.
empty_rlist = None
#Representation - start
#Constructor
def rlist(first, rest):
return(first, rest)
#Selector
def first(s):
return s[0]
def rest(s):
return s[1]

What is wrong with this pattern which emulates AsyncTask functionality?:

I have have attempted to use generics and constraints to create functions that retrieve and save data from a number of similar objects. Each of these objects describe their own properties. When I use these methods for a particular Type I don't understand why I have to specify new() in the constra...

I have question on how to print a character from a character array pointer:
#define C_ARR_SZ 100
typedef char c_arr[C_ARR_SZ];
typedef struct1
{
c_arr a;

};
void tes(void)
{
char addr[1000];

I have written the below code for inserting an element at the position specified by the user. Though i have seen the code in multiple books for insertion of node in the list and everywhere they have used two pointer in the function which is inserting the node at specified position . But in my cod...
I would like to understand how to get rid of all the loops I am using in this code.
I have a dataframe of 20 rows. I am simply counting the number of occurences that the variables rs and occ appear together.
Here is the data :

hey guys here is my problem. I am new to programming, and I am probably making a rookie mistake. In the line that reads "public var speed:Float = 200;" I keep getting "unexpected public" Error. What does this mean and what am I doing wrong?

Are the words isomorphs? (Code-Golf)
This is my non-golfed, readable and linear (quasi-linear?) in complexity take of the above problem. For completeness I include the description:
Two words are isomorphs if they have the same pattern of letter
repetitions. For example, both ESTATE and DUE...

Given [1,2,3], I wrote the following to get [[1],[2],[3]]:

Is this usage of return idiomatic in Haskell? I'm asking since I could've also used pure instead.
First of all, we have this question from four years ago:
Check if a subview is in a view
Despite carrying an Objective-C tag, ultimately this question is purely just asking about an object/method out of UIKit, which is one of the frameworks for writing iOS application. And even though the "pse...
I'm writing a function to reverse a number in Ruby. IE, 314159.reverse should return 951413.
Here's what I have, which works:

str = self.to_s.reverse
if self.is_a?(Float)
return str.to_f
elsif self.is_a?(Integer)
return str.to_i
end
