Collections reverse order class is a reverse order method, which is encoded in the collections class. It is present in the java.util package. It returns a comparator as a result, which is a predefined comparator in nature. By using this comparator package, we can rearrange the collections of a particular data set in a reverse manner. There are two different variants of the Java reverseOrder(), which can be defined as per the capacity of their parameters. Those are − Java Collections reverseOrder() Method − is used to get the value of a comparator class which can impose the reverse ... Read More
Assume we have a data set of some numbers as a string and denoted as str[]. Now the task is to multiply the two large numbers which represents a string here. We need to find out from those two numbers as strings, find if one is a power of other. Here is a general example of the process − Input for the process us: a = "374747", b = "52627712618930723" Output : YES THE VALUE IS HERE Explanation of the process: 374747^3 = 52627712618930723 Input for the process is : a = "2", b = "4099" Output : NO ...

In a C++ environment, the palindrome is a process where a set or string remains same from the intial stage of the process to termination of that same particular process. Assume, we have a string denoted as the str[]. And the task is to check the string will be paindrome or not after performing the swapping process with only one character for once. Here is a general example of the swapping process − Input : ARBRDD Output : true Explanation: Swap the value A(1st index present in the list) with the R. Input : INDBAN Output : true Explanation: ...

The reverse() is a pre-installed and predefined header file, which is used to define as a template in a process in a C++ environment. The method is able to reverse the elements from last to first manner in a range for any value container. For this process the time complexity is O(n). Lets assume, we have a string or a sentance declared as str[] with some data elements and now the task is to perform reverse process after removing the vowels from that string to get the final outcome. Here is some general examples of the process method − ... Read More

In a C++ environment, the palindrome is a characteristics where we get the same value after getting the result. Assume, there is a string denoted as S and the length is N. Now we need to run an operation on that string to find the palindromic characteristic is the number of k-palindromes in a given range. Here is a general example of the process − Input for the process : abba Output by the process : 6 1 0 0 Explanation of the method: "6" 1-palindromes numbers operation = "a", "b", "b", "a", "bb", "abba". "1" 2-palindromes numbers operation ... Read More
The opacity property is used to create a transparent textbox. Set an image in the transparent box using the background property. Since, we have set the opacity, it will make the text and image appearing in the text box to be transparent. Create a div container A div container is set − This is some random text inside the transparent box Transparent textbox Within the above parent div, the textbox child div is set − This is ...

Apply styles to HTML elements with particular attributes using Attribute Selectors in CSS. Let us see which attribute selectors are available with the rules. The [attribute] Selector The [attribute] selector selects elements with a specified attribute. Here, the link with the attribute target is styled − a[target] { background-color: red; color: white; } Example Let us see the example − a[target] { background-color: red; ... Read More
CSS can help us style the first letter of an element using the ::first-letter pseudo-element. Note that punctuation marks, digraphs and content property can change the first-letter. The following examples illustrate CSS ::first-letter pseudo-element. Style the first letter The first letter of all the elements, such as and here are styled using the ::first-letter pseudo element − ::first-letter { font-size: 3em; color: sienna; box-shadow: -10px 0 10px green; background-color: gainsboro; } Example Let us see the example − ...

Using CSS pseudo selectors, namely, :active, :hover, :link and :visited, we can style different states of a link. For proper functionality, the order of these selectors is given by:- :link, :visited, :hover, :active. Syntax The syntax of CSS text-indent property is as follows − a:(pseudo-selector) { /*declarations*/ } The following are some key Pseudo-classes for links − :active = To select the active link :hover = To select links on mouse over :hover = To select links on mouse over :valid = To select elements with a valid value :visited = To select ...
