Theoretical Computer Science

Usually, computer science seems like a practical field that involves studying, building, and working closely with computers. However, a subclass of this discipline also centers on the mathematical factors of the same. This is called theoretical computer science, and its focal point differentiates it from other branches of computer science: the rigorous mathematical approach it takes. This discipline falls under the umbrella of discrete mathematics, which is the study of countable or discontinuous mathematical structures.

A02-02 Create a webpage A2-Task2.html. The webpage is displaying one image. Each time the user moves the mouse out of the image, the image is changed to another one and one more 'sun' emoji is displayed under the image. When the number of 'suns' reaches seven (7), all suns are deleted (reset) and start to be displayed again. For example, the 8th time user moves the mouse out of the image, one 'sun' is shown, the 9th time - two 'suns', and so on. Note: - You should use two images. Each time the user moves the mouse out of the image, the image is changing. If an image of "Winter" is displayed it will change to "Summer", and opposite, if an image of "Summer" is displayed it will change to "Winter". The special character code for the 'sun' is "☀". - Put the source code of your website A2-Task2.html here. Make sure you also upload the A2-Task2.zip of all files below.
