In this problem, we will count the number of binary strings of size N, containing at most 2 adjacent distinct pair of characters. It means the string should contain, at most, 2 '01' 0r '10' pairs. The first approach is that generate all binary strings, and if any binary string contains less than or equal to 2 distinct pairs of characters, include its count in the result. For the optimal solution, we can count a number of binary strings containing 0, 1, and 2 adjacent different pairs and sum them. Problem statement - We have given a positive ... Read More
Python provides a wide extent of string control capabilities, making it a flexible dialect for dealing with printed information. In this article, we are going to discuss the concept of extending duplication in Python strings. Extend duplication includes copying a specific run of characters inside a string, thereby creating a modified version of the initial string. We are going investigate three diverse approaches to attain run duplication, talking about their calculations, step-by-step execution, and giving sentence structure illustrations. So, let's get begun! Advantages of Range duplication in Python String Modification of Substrings − Run duplication permits you to ... Read More
In this problem, we need to count substrings containing a minimum 1 occurrence of all K characters. Here, we will use two different approaches to solve the problem. The first approach takes all substrings of the given string, checks whether the substring contains all K characters, and counts such substrings containing all K characters. The second approach uses the sliding window technique to solve the problem. Problem statement - We have given a string alpha containing N characters. Also, we have given K, representing the string containing multiple occurrences of only the first K alphabetical characters. We ... Read More
Python gives an assortment of capable highlights and libraries for information control and investigation. When managing complex information structures, such as records of records, it can be advantageous to decide the number of records contained inside the list. In this article, we are going investigate three distinctive approaches to check the number of records in a list of records utilizing Python. We'll demonstrate the calculations, steps, and sentence structure, went with by code cases and yields, to assist you get it and apply these procedures viably. Approach 1: By using Iterative Approach method The primary approach includes utilizing ... Read More
In this problem, we will count the number of strings containing query string as a prefix for each query string. We can traverse the list of query strings, and for each query, we can find a number of strings containing it as a prefix. Also, we can use the trie data structure to solve the problem. Problem statement – We have given an strs[] and queStr[] string array containing N and Q strings, respectively. We need to count the number of strings from the Strs[] array containing the queStr[i] string as a prefix for each string of ... Read More
Working with information in Python frequently includes controlling records, which are basic information structures. In any case, managing duplicate values inside a list can display challenges. Whereas evacuating duplicates may be a common errand, there are circumstances where altering duplicate values and protecting the large structure of the list becomes necessary. In this article, we'll investigate different approaches to handle this particular issue. Instead of evacuating copy values, we'll center on changing them. Modifying copy values can be valuable in different scenarios, such as recognizing between unique and copy passages or following the recurrence of copies. Altering Duplicate Values in ... Read More
The range is something that has a limited number of elements and some may be mentioned along with the starting and ending elements The methods to check the range occurrences can be varying and some may be a simple way on the other side it can be determined using a library. In Python programming, there are different ways to find whether an element is present inside the given range or not and it can be done using various methods. Check Element for Range Occurrences Some popular methods to check for the occurrences are discussed and there are also ways ... Read More
In this problem, we will check whether it is possible to convert string S to T by incrementing the characters of S only once according to the given condition. Here, we can increment any characters by 'I' only once. So, If we need to increment any other character by 'I' times, the value of K should be greater than 26 + I. Problem statement – We have given a string S, T, and positive integer K. We need to convert the string S to T by following the rules below. We can take ... Read More
In this article, the user will understand how to remove all strings from a list of tuples in Python. When working with a list of tuples in Python, it's common to come across circumstances where you wish to expel any strings shown within the tuples. Evacuating strings from a list of tuples can be achieved utilizing different approaches. In this article, we are going investigate three distinctive strategies to achieve this task. These methods incorporate utilizing list comprehension, the filter() method with a lambda work, and a for loop with tuple unloading. Approach 1: Utilizing List Comprehension One of the ... Read More
Sometimes to maintain the uniqueness of all values available in a workbook, we require to eliminate duplicate values from the dataset. A case of duplicity may arise when there are two columns having email addresses and you want to find the repeating ones in one of the columns. This can be achieved using the below steps. Comparing two columns of Email Addresses to Find the Same values using Formula Step 1: We have taken a sample data as following. Here we have taken two columns having some email addresses and a third column in which we will display ... Read More
