Next greater number on the basis of the precedence of digits
In the normal number system, 0 is the smallest digit while 9 is the largest digit. In this problem, we will be given a list of the length 10, and starting from index 0 to index 9 it represents a digit, which indicates the priority of that digit and the list will be in increasing order means the digit present at the last index is the with highest priority. We will be given a number also and we have to find the next number which is the just greater than the current number. Input 1: Given number = “123” ...
Read MoreCheck if the given String can be split only into subsequences ABC
A subsequence of a string means part of a string in which characters can be taken from anywhere of the string (zero or more elements) without changing the order of the characters and forming a new string. In this problem, we have given a string of length N where every character of the string belongs to either ‘A’, ‘B’, or ‘C’ character. Our task is to find that the string can be split only into subsequences “ABC” or Not. If the string is split only into subsequences “ABC” then return “yes” otherwise return “no”. Input 1: str = “AABCBC” ...
Read MoreCheck if the Decimal representation of the given Binary String is divisible by K or not
A binary string is a string that consists of only two different types of characters and that is ‘0’ and ‘1’, hare base is 2. And a decimal representation means each digit is lie between ‘0’ to ‘9’, here the base is 10. Here we have given a string of binary numbers and an integer k. we have to check if the decimal representation of the given binary string is divisible by k or not. If it is divisible then we have to return ‘yes’ otherwise return ‘no’. In the conversion of binary to decimal, we convert a base 2 ...
Read MoreMaximize the sum of selected numbers from an array to make it empty
We will be given an array and have to choose an element from it and add that element to the sum. After adding that element to the sum, we have to remove three elements from the array if they exist current number, current number -1, and current number + 1. By this method we will make the array empty and will get a sum. At the end, we have to make the sum maximum. Input: [ 1, 2, 3] Output: 4 Explanation At first, we can have three moves, delete 1, 2, or 3. Let ...
Read MoreHow do I copy a file in python?
One of the most prevalent activities in modern software development is copying files programmatically. In today's quick tutorial, we'll look at a few different ways to transfer files in Python using the shutil module. Shutil is a Python Standard Library module that provides a wide range of high-level file operations. Now, when it comes to file copying, the library provides a variety of options based on whether you want to copy metadata or file permissions, as well as if the destination is a directory. It falls within the umbrella of Python's basic utility modules. This module aids in the automation ...
Read MoreHow to work with a text file in Python?
For creating, reading, updating, and removing files, Python includes a number of functions. When reading or writing to a file, the access mode determines the kind of operations that can be performed on the file. Creating a file using Python To create new files or open existing files, we can use the open() function. This function accepts two parameters: a string value representing the name of the file you need to create and a character representing the access mode of the file that is to be created. Following is the syntax of this function. File = open("txt_file_name" ,"access_mode") ...
Read MoreLongest Common Prefix in Linked List
The longest common prefix problem is a well-known computer science problem that is frequently encountered when working with strings or lists. It entails determining the string or list element with the longest common prefix. When it comes to linked lists, there are several approaches that can be taken. One common approach is to traverse the linked list and compare the characters of each node in the list until a mismatch is found. The longest common prefix up to the point of mismatch is considered. Linked List A linear linked list can be defined as a collection of variable number of ...
Read MoreQueries To Evaluate The Given Equation In A Range [L,R]
The evaluation of all equation in an interval [L, R] give us a range of values for those variables. Examples of how this may be used include modelling, data analysis, and problem-solving scenarios. In this situation, we define equations variable values for all point in range. Hence can be done by specifying the step size of the range and evaluating the equation for each variable value inside the range. Specifications It may be called a request for information asked to database. Data is extracted using specific commands when certain requirements are met. To acquire, filter, sort, and summarize data from ...
Read MoreFind Values after N Operations to Remove N Characters of String ‘S’ With Given Constraints
What are the Specifications of Using String? To solve a specific challenge involving the given string S. The string S contains only lowercase English letters, and certain constraints must be followed while removing characters. The given constraints are − There are lowercase English letters in string S. A character can only be deleted if it appears more than once in string. Only characters that appear consecutively can be deleted. The following steps can be used to remove characters from string S − Find all characters that appear more than once as you iterate over string S. Find all of ...
Read MoreSum of Indices of Characters Removed to Obtain an Empty String Based On Given Conditions
String manipulation-related concepts like The Sum of indices of Characters deleted to obtain an Empty String are frequently utilized in programming challenges and competitions. The result is then computed using the sum of the eliminated characters' indexes. The Sum of indices of Characters deleted to obtain an Empty String is a practical idea in string manipulation that may be used to solve a variety of programming difficulties and challenges. Problem Approach We must first comprehend the problem statement and given criteria to find total of character indices eliminated to produce empty string. Given string S, the objective is to determine ...
