Within the field of computer science, productive task scheduling plays a pivotal part in optimizing resource allocation and assembly time constraints. Scheduling with deadlines is a principal concept that spins around allocating tasks or processes to resources while considering time limitations or deadlines. The objective is to ensure that tasks are completed within their assigned time limits, minimizing lateness, and ensuring timely execution. This article explores the concept of scheduling with deadlines in computer science, its significance in different spaces, and the approaches and procedures utilized to meet time constraints. It dives into the challenges related to scheduling tasks within ... Read More
In MATLAB programming, we can use various types of built-in functions to generate different types of random numbers. Random numbers are nothing but numbers selected randomly from a set of numbers. MATLAB provides the following four major functions to generate different types of random numbers depending on our requirements: rand() randn() randi() randperm() Let us discuss each of these four ...

Matplotlib is a popular data visualization library in Python that provides a wide range of tools for creating interactive plots and charts. One of the interactive components offered by Matplotlib is the RadioButtons widget, which allows users to select a single option from a group of mutually exclusive choices. While working with RadioButtons, you may encounter situations where you need to resize them to better fit your plot or application layout. In this article, we will explore different methods to resize Matplotlib RadioButtons. Syntax radio_buttons.ax.set_position([left, bottom, width, height]) Here, radio_buttons refers to the instance of the RadioButtons widget. ... Read More
File permission in a Linux environment provides privileges to the owner or administrators to execute programs or applications. Permissions are set for the files or directories using chmod and chown commands with read, write and execute notations. Special permissions such as setuid, setgid, and sticky bits are initiated for executable files or directories; the user needs to pay more attention when these special permissions are set because they may impose security risks to all other users. Each file present in the directories has userId termed as uid and groupId as gid specified by the owner of the file, to execute ... Read More
In the operating system, segmented paging provides better performance and utilization of the CPU as it combines the process of segmentation and paging. Segmentation is termed a memory management technique where the memory is divided into segments that can be allocated to a process. These segments may not be in fixed length and not stored in a contagious manner. The segment table holds all the details relating to the segments and the processes. Generating a logical address which is converted to a physical address by the CPU by refereeing to the segment table. This table contains two fields about the ... Read More
Time series data is a sequence of observations collected over time at regular intervals. This data can be of any domain such as finance, economics, health, and environmental science. The time series data we collect can sometimes be of different frequencies or resolutions, which may not be suitable for our analysis and data modeling process. In such cases, we can Resample our time series data by changing the frequencies or resolution of the time series by either upsampling or downsampling. This article will explain different methods to upsample or downsample the time series data. Upsampling Upsampling means increasing the frequency ... Read More
Scheduling algorithms in the operating system execute the processes based on their arrival time or by their priority. Each algorithm chooses the processes that are in waiting to ready queue by preemption or non-preemption methods. Preemptive algorithms provide access to the CPU to the process which has higher priority and preempt any other process which is already running with lower priority. But in the case of non-preemptive scheduling, when processes start their execution, it cannot be preemptive even when higher priority processes are in the ready state. The traditional round-robin scheduling algorithm is a preemptive one where each process gets ... Read More
Problem Statement We have given string str and a binary string B. The length of both strings is equal to the N. We need to check if we can make string str palindromic by swapping the characters of it multiple times at any pair of indices that contains unequal characters in string B. Sample Examples Input str = ‘AAS’ B = ‘101’ Output ‘YES’ Explanation We can swape the str[1] and str[2] as B[1] and B[2] are not equal. The final string can be ‘ASA’. Input str = ‘AASS’ B = ‘1111’ Output ‘No’ Explanation ... Read More
In Python, tuples are immutable sequences that can contain a collection of elements. We can multiply all the items in a tuple using various methods like using a for loop, using the reduce() function from the functools module, using list comprehension, and the math.prod() function, etc. In this article, we will explore all these methods and implement the functions to multiply all items in a tuple in Python. Method 1:Using for loop This method is straightforward and easy to understand. It involves iterating over each item in the tuple and multiplying them one by one using a for loop. Syntax ... Read More
In C++, the string is a collection of various alphanumeric and special characters. We can create a string using the ‘string’ data type in C++. Problem Statement We have given a length of the string and one single character, and we require to generate a string of a given length containing the single character. In C++, we can define the string of a particular length by hard coding the values, but when we require to generate a string of different lengths and use the given character, we require to use the below approaches. Sample Examples Here are the sample ... Read More
