In python we can use not operator or subtraction operation as well as counter function to the number that are in range but not in set. A Python set is a grouping of unsorted elements. The set's elements must all be distinct, and unchangeable, and the sets must eliminate any duplicates. Sets can be changed after they are created because they are mutable. Example Assume we have taken an input set and range Input inputSet = {3, 10, 2, 11, 15, 4, 1} lowIndex, highIndex = 0, 8 Output [0, 5, 6, 7] Here 0, ... Read More
To find the tuple indices from other tuple list we can use enumerate function and index function of Python. An ordered and immutable group of objects is referred to as a tuple. Sequences are just what tuples and lists both are. Tuples and lists vary in that tuples cannot be altered, although lists may, and because tuples use parentheses while lists use square brackets. Example Assume we have taken an input list containing tules and another search tuple list. We will now search the indices of the search tuple list in the given input list Input inputList = [(1, 3), ... Read More
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 extract dictionaries with the maximum number of keys. Methods Used The following are the various methods to accomplish this task: Using for loop and len() function Using list comprehension and max() function Example Assume we have taken an input list containing multiple dictionaries. We will now extract dictionaries ... Read More
In Python, strings are among the most often used types. These are easily made by simply surrounding letters in quotations. Python treats single quotes and double quotes the same way. Assigning a value to a variable and creating a string is really straightforward. In this article, we will learn how to expand a character frequency string in python. Methods Used The following are the various methods to accomplish this task: Using zip() and join() functions Using re(regex) module and join() function Without using any built-in functions Example Assume we have taken an input string containing characters followed ...

In this problem we have to validate that a given number is a power of n. If the given number is power of n then it should return the true value of it otherwise it should return false. To check this kind of validation we generally use arithmetic operators like Modulus - %, Division - /, comparison operators like less than < or greater than >. Lets understand this problem with an example. True value: N = 27 So 33 = 27 False Value: N = 28 So 33 != ... Read More
In python we are can use simple for loop and max, count and operator function to find the maximum value from the dictionary whose key is present in the list. 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. Example Assume we have taken an input dictionary and input list. We will now find the maximum value from an input dictionary whose key is also present in the input list. ... Read More
As the problem stated, create a program for a unique sort in javascript. Basically we have to remove duplicate elements from an array. Understand the problem In this problem statement we need to eliminate the same or duplicated item from an array. For solving this kind of problem we can use some predefined methods of javascript. In this article you will be able to learn usage of forEach(), spread operator, set() method, filter() method and indexOf() methods. Lets understand this problem with an example. Array before sorting and with duplicates [535, 646, ... Read More
The problem statement is saying that we have to find a solution for a given array and split it to form an object with a key-value pair in javascript. Understand the problem In simple terms we have to convert a given array into an object. There are several methods present in javascript to convert an array into an object. We will use and code each of them one by one. Using reduce() and split() methods In this method we will use reduce and split functions of javascript. Algorithm The algorithm here discusses ...

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 how to extract keys with specific value type in python. Methods Used The following are the various methods to accomplish this task − Using for loop and isinstance() method Using list comprehension and isinstance() method Using keys() & type() methods Example Assume we have taken an input dictionary. We will now Input ... Read More
In this problem, we have to group all the duplicate data in the array by making their subarray. After making the subarray we have to arrange them in a sorted order. This problem can be solved by searching techniques of data structures. Understanding the Problem So for solving this problem, we will use javascript’s reduce() method in two ways. The reduce method is an iterative method which uses a reducer function to iterate through all the items in the array. So by checking one by one we will keep track of all the elements and ... Read More
