This example will help to verify the given time is within a period or not. To check the time is today, We can use DateUtils class boolean isToday = DateUtils.isToday(timeInMillis); To check the time is within a week, private static boolean isWithinWeek(final long millis) { return System.c...

Developers often need to design web sites that allow users to upload a CSV file. Usually there is no reason to save the actual CSV file since the data will processed and/or stored in a database once uploaded. However, many if not most, PYTHON methods of parsing CSV data requires the data to be rea...

The most basic implementation of a union-find data structure consists of an array parent storing the a parent element for every element of the structure. Following these parent 'pointers' for an element i leads us to the representative j = find(i) of the set containing i, where parent[j] = j holds....

If we do many merge operations on a union-find data structure, the paths represented by the parent pointers might be quite long. Path compression, as already described in the theory part, is a simple way of mitigating this issue. We might try to do path compression on the whole data structure after...

In our current implementation of merge, we always choose the left set to be the child of the right set, without taking the size of the sets into consideration. Without this restriction, the paths (without path compression) from an element to its representative might be quite long, thus leading to la...

Configuration First, create a file called Package.swift. This is the file that tells swift compiler where the libraries are located. In this hello world example, we are using GitHub repos. We need Kitura and HeliumLogger. Put the following code inside Package.swift. It specified the name of the pro...

In cases where you need to ensure model validation using Jquery, .valid() function can be used. The model class fields [Required] [Display(Name = "Number of Hospitals")] public int Hospitals{ get; set; } [Required] [Display(Name = "Number of Beds")] public int Beds { get; ...

Use Nuget to find the Web Api Package. You can do that either by using the Manage Nuget Packages and searching for the Web Api package or use Nuget Package Manager and type PM> Install-Package Microsoft.AspNet.WebApi Add WebApiConfig.cs to the App_Start/ folder The config file should contain...

From this website, the OP has noticed a problem. Cause Consider the following code snippet. if 1==1 ( set /a result = 2*(3+4) ) At your first glance, you may think CMD.exe would process it like so: The condition is true, execute code block Set variable result's value to 14 Continu...

Another heuristic commonly used instead of union by size is the union by rank heuristic Its basic idea is that we don't actually need to store the exact size of the sets, an approximation of the size (in this case: roughly the logarithm of the set's size) suffices to achieve the same speed as union...

While in combination with path compression, union by rank nearly achieves constant time operations on union-find data structures, there is a final trick that allows us to get rid of the rank storage altogether by storing the rank in out-of-bounds entries of the parentarray. It is based on the follow...
