Binary (or base-2) a numeric system that only uses two digits — 0 and 1. Computers operate in binary, meaning they store data and perform calculations using only zeros and ones. A single binary digit can only represent True (1) or False (0) in boolean logic.1. Binary is a base-2 number system invented by Gottfried Leibniz that is made up of only two numbers: 0 and 1. This number system is the basis for all binary code, which is used to write data such as the computer processor instructions used every day.

Answer:
Explanation:
Let's do this in Python, first we need to convert the number into string in order to break it into a list of character, then we can replace the kth character with d. Finally we join all characters together, convert it to integer then output it
def setKthDigit(n, k, d):
n_string = str(n)
d_char = str(d)
n_char = [c for c in n_string]
n_char[k] = d_char
new_n_string = ''.join(n_char)
return int(new_n_string)

Explanation:
World Wide Web (www) has advanced as a major technology since its introduction during the 1980s. In beginning web sites were primarily used only by few number of users to share information related to their academic work. As the user interface evolved over the next coming years with each new version bringing in new frameworks and techniques, it powered web as a hub of technology. Web 1.0, 2.0 and 3.0 brought more dynamic features to the users. Web 1.0 used to describe the web content in static resulting in rigid user experience. Web 2.0 which powered social networking sites became popular developing the web which ultimately served as a platform for people to create and share their own content on the web in the form of blogs, wikis, feeds, tagging systems, user-created publication systems etc. The evolution of web technology began to spread its roots into the major business areas which brought in the requirement for high speed and expanded availability for substantial number of users.
On the other hand, Web 2.0 has also brought some security’s concerns. Mainly the component of client interaction with web, it opened doors to unauthorized actions in the application. In order to provide a rich user experience majority Web 2.0 sites have adopted lightweight user interface code such as asynchronous JavaScript and XML (AJAX). In the Conventional client-server models, many of calls (requests) are handled and processed on the server side. AJAX allows a higher percentage of requests to be processed on the client side. This may give malicious users many options to modify any application code running on a client machine by exploring and testing the application for vulnerabilities.
To overcome this objective, developers should consider installing an appliance at the Internet gateway, which performs real-time code inspection of traffic flowing through the corporate network. High performance and high availability appliances capable of monitoring and acting swiftly to block any suspicious web traffic are paramount. Also, it is very important that developers develop the application with security in mind. Following the coding convention, having the code reviewed, testing the application thoroughly are all part of securing the application in the web.
