Dear Student,

You choose CSE branch only if you are interested in coding/programming otherwise you will not succeed in this field.

And in programing you don't need to learn the long codes you just need to know the syntax of that particular language whether it is a C/C++/Java/Python. Rest part is just the logic and you can modify that if you can and make that code short. You need to improve your logical thinking so that you can write good code without learning.

Good Luck :)
