In this article, we will discuss how to check if the characters of each word in a given string can be rearranged to form an Arithmetic Progression (AP). We will also implement the solution in C++ and provide an example to illustrate the working of the code. Arithmetic Progression (AP) An Arithmetic Progression (AP) is a sequence of numbers in which each term after the first is obtained by adding a constant d to the preceding term. The constant d is called the common difference. For example, the sequence 1, 3, 5, 7, 9 is an Arithmetic Progression with common ... Read More
In this article, we'll delve into an intriguing problem in the field of string manipulation: how to check if the characters of a given string can be made non-decreasing by replacing '?' characters. This problem provides an excellent opportunity to hone your skills in string manipulation and condition checking in C++. Problem Statement Given a string consisting of alphabetic characters and question marks (?), determine whether the characters can be made non-decreasing by replacing the '?'s. The non-decreasing condition means that for every two adjacent characters in the string, the ASCII value of the second character is not less than ... Read More
In this article, we will explore the problem of checking whether all strings of an array can be made the same by interchanging characters. We will first understand the problem statement and then investigate both the naive and efficient approaches to solve this problem, along with their respective algorithms and time complexities. Lastly, we will implement the solution in C++. Problem Statement Given an array of strings, determine if all strings can be made the same by interchanging characters. Naive Approach The naive approach is to sort the characters of each string in the array and then compare each sorted ... Read More
In computer science, hexadecimal is a base-16 number system. It uses 16 distinct symbols, including the ten decimal digits from 0 to 9 and the six letters A, B, C, D, E, and F to represent numbers from 0 to 15. In this article, we will discuss how to check if a string represents a hexadecimal number or not. Problem Statement Given a string, the task is to check if it represents a valid hexadecimal number or not. Approach We can solve this problem by iterating over the characters in the string and checking if they belong to the set ... Read More
Welcome to another in-depth guide on a fascinating problem-solving topic in C++. This time, we will be tackling the problem of determining if a string can be divided into two substrings, each containing an equal number of vowels. This problem is an excellent exercise for honing your skills in string manipulation and vowel counting. Problem Statement Given a string, our objective is to determine if it can be partitioned into two non-empty substrings such that both substrings have an equal number of vowels. The vowels in the English alphabet are 'a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'. ... Read More
The problem statement says that we have to find the minimum value present in each record value list. So in this article we will see different ways to find the minimum in each record. Understanding the problem In the given problem we are required to find the minimum value of each subarray. For example: let’s say we have an array as [[8, 10, 12], [12, 14, 16], [17, 18, 19]], so in this example we can see the minimum values for every subarray are 8, 12, 17 as these arrays are in a sorted form. So the required result should ... Read More
In the given problem statement, we have to find the minimum product pair in the given list and list of tuples. So we will use Python to implement the code. Understanding the Problem The problem at hand is to find the minimum product from the given list and create a program in Python. Or we can say that we have to find the pair of numbers whose multiplication is minimum as compared to the other pairs in the list. There are many ways to solve this problem. So we will use list and list of tuples to showcase this ... Read More
The problem at hand is to find the minimum value from the given tuple list using python programming language. So basically whenever we talk about finding the minimum value we use the min function defined in the built-in function of Python. In this article we will see different approaches to get the minimum value from the tuple list. What is the tuple list or list of tuples? The tuple list or we can also say list of tuples, is a data structure in Python programming. Tuple list contains multiple tuples as its items. Or we can say that every element ... Read More
The problem we have is to find the minimum identical consecutive subarray in the given array and implement this algorithm using Python. So we will use basic functionalities of Python to get the desired result. Understanding the Problem In the given problem statement we are required to find the shortest identical consecutive subarray present in the given input array. So we will be having an array with some repetitive items and we have to show the subarray with minimum repetitive items count. For example: suppose we have an array as [0, 0, 2, 2, 2, 3, 3, 3, 3, 5, ... Read More
In this article we will be creating the multi tabbed Notebook Graphical user interface with the help of Python GTK + 3. So we will be creating a window which will look like a notebook. Understanding the Problem The problem at hand is to create a notebook using Python GTK + 3. If the GTK + 3 package is not installed on your system then we can install this package with the help of command ‘pip install pygobject’ or using ‘MSYS2’ packages in windows. So we will create a window and inside the window there will be two tabs or ... Read More
