Introduction In recent years, deep neural networks (DNN) have made significant progress in reinforcement learning algorithms. In order to achieve desirable results, these algorithms, however, suffer from sample inefficiency. A promising approach to tackling this challenge is episodic memory-based reinforcement learning, which enables agents to grasp optimal actions rapidly. Using episodic memory to enhance agent training, Episodic Memory Deep Q-Networks (EMDQN) are a biologically inspired RL algorithm. Research shows that EMDQN significantly improves sample efficiency, thereby improving the chances of discovering effective policies. It surpasses both regular DQN and other episodic memory-based RL algorithms by achieving state-of-the-art performance on Atari ... Read More
In this problem statement we are required to multiply K to every Nth item in the given list or sequence and implement the solution using Python. So We will solve this problem using basic Python programming. Understanding the Problem The problem at hand is that we have to multiply a specific value called K to each Nth item in the given list. Generally we create a function to apply on each item of the list but here in our problem we have to multiply a constant with some items in the list. To understand better let’s dive in the ...

In the given problem statement we have to multiply the consecutive items in the given list with the help of Python programming language. So we will create the code using basic functionalities of Python. Understanding the logic for the Problem The problem at hand is to multiply each element with its adjacent element in the given list. So for multiplying the consecutive elements we will iterate over the list and multiply every element with the adjacent element. So basically we will start multiplying by the first item with the second item in the given list. And then the second item ... Read More
In the given problem statement we have to create an algorithm for multiplying two lists using Python. There can be many situations in which we can use this approach like Data Preprocessing, Combining Information, Scaling values and much more.So we will demonstrate different methods and algorithms to do this kind of work. Understanding the Problem The problem at hand is to calculate the multiplication of two given lists using Python. So basically we will be given two common lists of Python and we have to multiply items of the first list with the items of the second list. For example ... Read More
The given problem is required to create a Python program to move a word to the rear end of the given string. So we will be having a Python code with the help of it we will be able to move the word to the specified place. Understanding the logic for the Problem The problem at hand is to move a word to the rear end of the given string using Python. So in this article we will use two approaches to perform the given task. In the first approach we will use the replace method of Python. And in ... Read More
In today's article, we will dive deep into a unique problem related to string manipulation in C++. The problem is "Digits whose alphabetic representations are jumbled in a given string." This problem can serve as an excellent exercise for enhancing your string manipulation and data structure skills in C++. Problem Statement Given a string, the task is to identify the digits whose alphabetic representations are jumbled within the string. For instance, if the input string is "oentow", it has a jumbled representation of the digit two (t, w, o) and one (o, n, e). C++ Solution Approach To solve this ... Read More
In this article, we will explore the concept of creating a custom Jumble Word Game in C++. Word puzzles are not only entertaining but also a great way to improve vocabulary and cognitive skills. We will walk you through the process of designing and implementing the game using C++ and provide a test case example to illustrate how the game works. Custom Jumble Word Game The objective of the Jumble Word Game is to unscramble a given set of letters to form a valid word. Players are given a jumbled word, and they have to rearrange the letters to form ... Read More
In this problem, we will find the number of pairs of 3 indices so that any adjacent indices don’t have the same value in the pair. We can get the output by checking each pair of 3 indexes, but it can be more time-consuming. Another approach to solving the problem is to take the current index and also take the index from left and right, which doesn’t contain a similar value to the current index's value. This way, we can count the total number of pairs each index can form and sum them to get the output. Problem statement − ... Read More
In this problem, we will count the number of substrings of the given string containing all characters with even frequency or any single character with odd frequency. We will use the bitmasking technique to solve the problem. In bitmasking, each bit of the binary string represents the character. Problem Statement We have given a string alpha of length N. It is also given that 'a'
In this article, we will examine the concept of counting the ways to place all characters of two given strings alternately. This problem can appear in programming challenges and interviews, and mastering the solution will help you improve your string manipulation and algorithm skills. We will explain the problem statement, discuss the algorithm used, present the C++ implementation, and provide a test case example to illustrate the solution. Problem Statement Given two strings s1 and s2, find the number of ways to place all the characters of both strings alternately, such that the characters from s1 and s2 are placed ... Read More
