Coding tips
Practice is the key to excel in coding. GeeksForGeeks, also known as the encyclopedia of coding has numerous questions with editorial so practice atleast 4 problems each day.
A little trick that I used is, maintain a notepad of the problems which are extremely tough for you and visit those problems on daily/ weekly basis. This will keep on reiterating the logic in your mind and you will get hold of it.
Never memorize the code. Understand the logic and practice the same code at regular intervals.
Learn to use the debugger. It's going to save a lot of your time if you practice fixing the error with the help of debugger.
And finally, code with passion. Never give up. It might be tough but keep on pushing yourself. You'll soon get there.
