Count Substrings that can be Made of Length 1 by Replacing \"01\" or \"10\" with 1 or 0
In this problem, we will count substrings that we can make of length 1 by replacing the ‘10’ and ‘01’ substrings with ‘1’ or ‘0’ characters. When any binary string contains an equal number of ‘0’ and ‘1’, we can always make it of length 1 by performing the replacement operations. So, the problem is solved by finding the substrings with equal numbers of ‘0’ and ‘1’. Problem statement − We have given a binary string named bin_str and of length bin_len. We need to count the total number of substrings that we can make of length 1 by ...
Read MoreCheck if given Morse Code is Valid
In this problem, we will validate the Morse code. The Morse code method was used to transform the text in the encoded format, and it was very helpful to provide communication between two entities before the telephone was invented. There are standard codes for each alphabetical character containing the ‘.’ And ‘−‘. The code is prepared based on the transmission time, where ‘.’ Represents the short signals, and ‘−‘ represents the long signals. However, in this tutorial, we will use the standardized Morse code to decode and validate the string. Here is the table of standardized Morse code. ...
Read MoreCheck if two Binary Strings can be Made Equal by Doing Bitwise XOR of Adjacent
In this problem, we will check whether we can convert string alpha2 to alpha1 by performing the XOR operation of any two adjacent characters and replacing both characters with an XOR value. We will use the logic based on the XOR value of two digits to solve the problem. If the string contains at least one ‘1’ and more than two adjacent consecutive characters, we can convert the alpha2 string to alpha1. Problem statement − We have given two binary strings of the same length. We need to check whether we can convert the alpha2 string to alpha1 by performing ...
Read MoreCheck if a String can be Converted to Another by Inserting Character Same as both Neighbours
In this problem, we will check whether we can convert the string alpha1 to alpha2 by inserting the same characters between any two same characters of the given string. We will use the run length encoding algorithm to solve the problem, which counts the frequency of the contiguous characters. Problem statement − We have given two strings named alpha1 and alpha2. We need to check whether we can convert the string alpha1 to alpha2 by performing an unlimited number of below operations. Choose any index, and the character at the current and previous index is the same, insert the ...
Read MoreCheck if a Character is Only Occurring as One Single Contiguous Substring or Not
In this problem, we will check whether all characters are present continuously in the given string. We will use the map data structure to solve the problem. The map will keep track of the last index of the particular character, and based on the last index of the current character, we will decide whether the string contains contiguous characters. Problem statement – We have given a string alpha of length N containing the lowercase and uppercase alphabetical characters. We need to check whether the given string is contiguous. The string is contiguous only if it contains all characters as a ...
Read MoreHow to set the width of the bottom border animatable using CSS?
In CSS, we can use the ‘border-bottom’ CSS property to set the bottom border for an HTML element. We can use the animation property to animate the width of the bottom border. Also, we require to define the keyframes by changing the width of the bottom border to animate it. Syntax Users can follow the syntax below to animate the width of the bottom border. selector { animation: mymove 5s infinite; } @keyframes mymove { 50% { border-bottom: 25px solid black; } } ...
Read MoreHow to reset selected value to default using jQuery?
While creating the web page, developers may require to reset the selected option for the dropdown menu. For example, we added the dropdown menu in the form allowing users to select any option. Once users submit the form, we require to reset the dropdown menu options using JavaScript or Jquery. In this tutorial, we will learn different approaches to resetting the selected value of the dropdown menu to default using Jquery. Using the prop() method The first approach uses the prop() method of Jquery. It allows us to reset the value of any property. Here, we can reset the value ...
Read MoreHow to replace an HTML element with another one using JavaScript?
In this tutorial, we will learn to replace an HTML element with another one using JavaScript. In some use cases, we require to replace a whole HTML element with a different one. For example, it is very important in the form validation. Suppose we are taking the user’s age from the form, and the user enters the wrong age; we can show the validation message by replacing the HTML element. Another use case where we require to replace an HTML element with another one is dynamic content loading, in which we must show the web page content based on certain ...
Read MoreHow to remove global CSS file from a particular page using jQuery?
Programmers require to use CSS while developing the web page to style the web page and make it attractive. We can add CSS to the web page in three ways: inline CSS, Internal CSS, and external CSS. To apply external CSS, we can import the CSS file in the tag using the tag. The external CSS file can also be a global CSS file. Sometimes, we require to remove the global CSS file from a particular web page. For example, you allow your web app users to switch between multiple themes, and when users switch the theme, ...
Read MoreHow to Remove Column from HTML Table using JavaScript?
In HTML, the table is used to show the data on the web page in a formatted way. The table contains the columns and rows to show the data. Sometimes, developers need to delete the table column or allow users to delete them. For example, the table contains the users’ data and has the ‘age’ and ‘birthdate’ columns. In such cases, we require to delete the ‘age’ column as we can get the age from the ‘birthdate’ column. Developers can use the deleteCell() method to delete any particular column. In this tutorial, we will learn to delete the ...
