In python an array(list) of comma-separated values (items) enclosed in square brackets is one of the most flexible data types available in Python. The fact that a list's elements do not have to be of the same type is important. In this article, we will learn a python program to check whether a number formed by combining all elements of the array is a palindrome. Methods Used The following are the various methods to accomplish this task: Using map() & join() functions Using type casting & string concatenation Using str(), list(), extend(), join() and reverse() functions Example ...

Python's implementation of a data structure known more commonly as an associative array is a dictionary. A dictionary is made up of a group of key-value pairs. Each key-value combination corresponds to a key and its corresponding value. In this article, we will learn a python program to convert URL parameters to dictionary items. Methods Used The following are the various methods to accomplish this task − Using urllib.parse.parse_qs() function Using setdefault() and re.findall() functions Using split() function Example Assuming we have taken an input string with URL parameters, we convert this query string to the ...

Python has internal functions lie count, counter and operator functions that can be used for printing all the repeated digits present in a number that too in sorted order. The following example will help you understand the concept more clearly. Example Assume we have taken an input string. We will now print all repeating/duplicate digits present in a given input number in sorted order using the above methods. Input inputNum = 5322789124199 Output 1 2 9 In the above input number, 2, 1, and 9 are repeated digits. So these digits are sorted in ascending ... Read More
In the given problem, we have to find out the average of every group of n elements in the array. If there are m elements in the array, then calculate the average of every group and show the result in array form. Understanding the Problem Suppose we have 6 elements in the array and make a group of 2 elements. Now calculate the average of every group individually. Now that we have their average values, we can combine them into a single array. To implement this problem we have used reduce(), push(), and slice(). These ... Read More
The Given problem is stating to count the duplicates of array elements and then aggregating objects in a new array. Understanding the Problem Problem statement is saying to identify the duplicate elements from an array and make a single array of those objects stating the counts. To solve this question we will use brute force technique with the help of for loops. What is an Aggregating Array of Objects? Aggregation in an array refers to combining down several objects in a new array as an output. We have to check if the aggregate of objects ... Read More
In this problem, we need to check whether the given number is an unsigned integer using the DFA. We need to construct the DFA using the 2D array to solve the problem. Problem statement – We have given string str of length N. By constructing the DFA, we need to check whether the str represents the unsigned integer. In the output, print ‘unsinged integer’ or ‘Not an unsinged integer’ according to whether the number is unsinged or not. Sample examples Input– str = "1729" Output– “Unsigned integer.” Explanation– As the number doesn’t contain any sign, it is an ... Read More
The problem is stating that we have to add two binary strings. Binary strings are a sequence of bytes. To add them in javascript, we will first convert them to decimal and calculate the sum. After adding those decimal numbers, we will convert it again into binary strings and print the output. What are Binary Strings? Binary numbers or binary strings are sequences of bytes in base 2. It is basically a combination of 0 and 1 to represent any number. While binary addition is one of the operations of mathematics to perform on binary strings. Binary addition ... Read More
In this problem, we need to check whether we can make two strings equal by rearranging the words of the string. We will learn three different approaches to solving the problem. In the first approach, we will use a dictionary. In the second approach, we will use the sort() method, and in the third approach, we will use the counter() constructor, which is used to count the hashable objects in the python. Problem statement – We have given a str1 and str2 containing sentences. We need to check whether we can make both strings equal by rearranging the words of ... Read More
A dictionary in Python is a built-in data structure that allows you to store and retrieve values using unique keys. It is an unordered collection of key-value pairs enclosed in curly braces {}. Dictionaries provide a convenient way to organize and manipulate data, making it easy to access values based on their corresponding keys. In this article, we are going to see how to convert Dictionary to Concatenated String using Python which means that all the keys and values of the dictionary will be combined in the form of a string as follows. Input = {'one': 1, 'two': 2, ... Read More
Data handling or organizing or structuring in Python has a lot of common tasks and 1 such task is the conversion of list to list of dictionaries. It is a simple process that allows us to associate specific keys with their corresponding values; creating a collection of dictionaries that can be simply accessed and/or manipulated. Before going forward with the techniques let us 1st see an example input and output. Consider the following: Input test_list = ['John', 25, 'Smith', 30, 'Alice', 35] key_list = ['name', 'age'] Output [{'name': 'John', 'age': 25}, {'name': 'Smith', 'age': 30}, {'name': 'Alice', 'age': ...
