Linux is a popular open-source operating system that offers many advantages, such as being free, customizable, and secure. One of the challenges that Linux users face is finding the right tools for certain tasks, such as compressing and decompressing files. Fortunately, 7zip is a powerful and versatile compression tool that can help us with this task. In this tutorial, we will walk through the process of installing and using 7zip in Linux. We will cover different ways to install 7zip, including via the command line and package manager, and provide step-by-step instructions with screenshots. We will also explain the basic ... Read More

In this article, I'll show you how to view configuration files without comments in Linux using a few simple commands. Removing comments from configuration files can help you more easily find the information you need and make modifications to system settings. We'll explore two methods to accomplish this task - using the grep and sed commands. With these methods, you can effortlessly streamline your Linux system's configuration files, making it easier to locate critical information and adjust settings as needed. If you need to remove comments from a configuration file in Linux, the grep command is a straightforward and efficient ... Read More
Making web pages mobile-friendly is a challenging task for the customs form control. jQuery gives us many options to perform the task conveniently. Since smartphones are very popular devices nowadays, it is important to be able to create custom form controls which visually appealing interfaces. jQuery library of JavaScript can help in building both responsive and engaging designs. In this article, we shall learn how to design form control for mobile using jQuery mobile Square-UI Theme plugin. Example This code demonstrates how to design mobile forms using the jQuery Query Mobile Square-UI Theme plugin. We first included the necessary libraries ... Read More
In this tutorial, we need to separate all 1s and 0s of the given binary string in the two halves. Here, we need to take a substring from the given string and reverse it to separate 0s and 1s in different parts. Ultimately, we need to count the total number of reversals required for substring to separate 1s and 0s in two halves. Problem statement − We have given a binary string of even length. We need to take any substring from the given string multiple times and reverse it to separate it into two halves. We need to print ... Read More
In this problem, we need to replace the characters of the given string according to the characters given in the array of pairs of characters. We will discuss two different approaches to solving the problem. In the first approach, we iterate through the characters of the given string and pairs of characters to replace each character. In the second approach, we will use an array of length 26 to store the replaced character related to each character and change the character of the given string. Problem statement − We have given a string str containing N lowercase alphabetic characters. Also, ... Read More
In this problem, we need to remove the minimum characters from the string and rearrange the remaining characters to make the string palindromic. To solve the problem, the first question we should ask ourselves is when we can make string palindromic. In below two cases, we can make string palindromic. If each character’s frequency is even in the given string. If only one character’s frequency is odd and all other characters' frequency is even. So, we need to remove minimum characters to make each character’s frequency even except for any single character. Problem statement − We have given ... Read More
In this problem, we require to remove all zeros from the given binary string. Also, we require to remove pair of consecutive zeros at once and count the total number of pairs of zeros removal. We can solve the problem by counting the number of pairs of consecutive zeros in the given string. In this tutorial, we will learn two different solutions to solve the problem. Problem statement − We have given circular binary string str of length N. We need to find the minimum number of consecutive zeros required to remove all zeros from the string. Sample Examples Input ... Read More
Here, we require to manipulate the binary string so that it doesn’t contain any consecutive zeros. If we find consecutive zeros, we need to change any zero to 1. So, we require to count the total number of 0 to 1 conversion we should make to remove all consecutive zeros from the string. Problem statement − We have given a binary string ‘str’ containing only 0 and 1. We require to find the minimum number of flips required so that the resultant string doesn’t contain any consecutive zeros. Sample Examples Input – 0101001 Output – 1 Explanation ... Read More
In this problem, we require to find the longest non-increasing subsequence of the given string. The meaning of non-increasing is either character should be the same or in decreasing order. As binary string contains only ‘0’ and ‘1’, the resultant string should start with ‘1’ and end with ‘0’, or start and end with either ‘0’ or ‘1’. To solve the problem, we will count prefix ‘1’s and suffix ‘0’ at each position of the string and find the maximum sum of prefix ‘1’s and suffix ‘0’s. Problem statement − We have given binary string str. We need to ... Read More
