I generally hear that to improve coding one should do Topcoder Div2 questions , but there are so many srm rounds . So I want to ask which srm contest to start from , like from the beginning or from the end . Which SRM rounds are better to improve skills .
Anything will do.
Just open one and solve problems there
Then repeat for as long as you want/can and you will improve in no time.
The right problems to start practicing are the ones you haven’t solved before
